<p>I've wondered if these types of casual open world, resource collection games-- which are basically a series of mini-games-- would make good model training envs. Each mini-game has a pretty simple mechanic that needs to be learned, as well as the navigation and interactions to begin it. Those could be pretty useful generic skills I think.<p>One of my side projects is a game, and I've made it so agents can spawn off their own world shard to play in. There's a little Chrome-driven agent harness that can grab low res screenshots while it speaks directly to the game over the wire to control things.<p>I've had Luna play it and it can drive around (you play as a bike) but it did struggle to play one of the mini-games (Disc Golf). My idea was that model trainers could run it an RL loop using the harness to get feedback data and screenshots to use, then reset the game world as needed during the process.<p>A smart model capable of multi-modal inference on screenshots/game context at 30-60fps could be pretty interesting, and I'm sure it's coming. No idea how much it would generalize but would be fun to see done.</p>

<p>Awesome! If you click the top left 'Mode' switch and go to Property, you can buy it :) you just have to pick up and scrap enough trash to get the $5k for it.<p>I do think 95 and 676 will be in the game more accurately eventually. But it will match the style of the rest of the game. It's a work in progress now but not good enough to ship yet. Love that you said bizarro, feels like i'm on the right track</p>

<p>Hey, thanks. You're pretty much right about highways. I do have a separate working branch that has actual raised highways, but I'm still figuring out the kinks in making it look nice and joining the terrain correctly. Generating accurate entrance/exit ramps has proven to be my kryptonite but I'll get it eventually. I will give the minimap some love when I get back too-- thanks for checking it out</p>

<p>For any Philly ppl here, I've been making this game for a few months: <a href="https://cityrider.jpsmaps.com/" rel="nofollow">https://cityrider.jpsmaps.com/</a><p>Similar concept, but more abstract in terms of art style. I'm pretty close to having the foundation I wanted before adding quests on top; telling a story is the ultimate goal.<p>Building on top of GIS data is super fun though. Especially since the barrier to entry is so low these days with LLMs. I encourage everyone to give it a shot if your local town/city publishes some data. No need to understand coordinate systems for example, which is nice.<p>For the game, there's a button to get in without an account so you can play around, but to get the fun mods you will need to play a bit and figure out the trash pick up/scrap at dump mechanic in the game.<p>(*might be a bit of lag; server needs more ram but on vacation rn!)</p>

<p>Just one data point, but I've been to many policing conferences since 2020 and I think one of the main drivers of the Flock problem is a disconnect between what the public understands 'crime prevention' to mean, and what is sold to police under the same verbiage. Something I believe strongly is that healthy public safety requires both responsive action and crime prevention. When I talk about this, I will show quadrants with axes for Give/Take and Planned/Responsive, and try to get people to classify their public safety activities to see where they fall. To me it should be somewhat balanced. Everything concentrated in Take/Responsive is an incomplete strategic plan.<p>However, most tools available to police are designed to be responsive; they help catch a criminal that has already done something bad. This is not crime prevention. Nothing was prevented. Anyone living in an American city knows these cameras don't prevent much.<p>It is also (unfortunately) a very vendor driven industry. IACP is a big deal each year, and Flock / Axon / Motorola go all out on spending to influence decision makers.<p>Talking to communities, in my experience, they ask for crime prevention. People want the actual incident to never have occurred in the first place. When vendors go around saying they are solving crime once and for all, but all they deliver is surveillance, it builds distrust. It feels like lying, while the companies themselves get rich on public money.<p>Then they go on huge PR campaigns to tell the public actually what they're feelings is wrong and they should accept the surveillance. It's silly.<p>In the policing communications world, people often say trust is built in drops, and lost in buckets.</p>

<p>Cool visuals and breakdown. I wrote something in early 2025 about how LLMs seem to be an emergent behavior of lossy compression, but did not have the knowledge or verbiage at the time to get this detailed. In retrospect my writing seems naive and I'm happy to have found this and the Google paper linked inside. To be a fly on the wall in some of the labs, man.<p>Another thought that came from the same post is that, insofar as we see LLMs as human-style intelligence, they're more like stream of consciousness devices. Essentially incessant talking and buying enough time until you get to a usable answer. I think I associate some subset of intelligence with what you <i>don't</i> say, which is impossible with the SOC-style outputs, so this is something I think about a fair bit.<p>What could maybe differentiate current gen models from next gen is the ability to call tools modeled within the layers themselves, not externally. I think as far as I understand it, model trainers expect the model to do this itself in a way we don't understand or control, like a version of the bitter lesson. But I posit we can model many determinate tools as NNs themselves and figure out how to get the internal states of the LLM to make use of them during inference, e.g. calculators, indexes, citations. Just an enthusiast though, so grain of salt and all.</p>

<p>I think doing this type of work makes you really respect the game devs that pioneered the genre. a lot of little things matter in terms of making it feel right, whether you're going for realistic or more arcade like.<p>for my version I leaned arcade: during the race you can jump higher, it gives in game direction hints, and the whole track has a ribbon on it so it's obvious where to go. however, every hour the track changes to a different stretch of Philly roads and it can definitely highlight your point.<p>The art direction and sense of scale are important, and successful games seem to be quite good at tricking you into thinking the visual scope is bigger than it is, while the smaller/tighter areas are easier to navigate in-game. The real world is surprisingly huge.<p>(I don't want to spam my game but you can find it in my recent comment history)</p>

<p>This is very cool. I concur on the conclusion that we'll soon see a lot more use of AI coding tools in gov as people discover what can be done with all these existing data sets. Would love to see more resources put into creating and publishing them. I'm sure there's plenty of ways for govs to make their money back on the data these days with some creative licensing.<p>Tangential, but I'm also a little obsessed with taking municipal data and turning it into something else. Lately I've been building an online open world game built on Philadelphia's terrain. It similarly uses a Philly LIDAR scan, the land use maps, the street data, building lots, and a few other sources to make the game map.<p>There's a signup but it doesn't validate or anything I just haven't gotten around to making a demo mode. Any fake email will do: <a href="https://cityrider.jpsmaps.com/" rel="nofollow">https://cityrider.jpsmaps.com/</a>. The general idea is to pick up trash around Philly to power/build other fun things like your jet pack and ramps. Buy properties and customize the facades. Run from Gritty. It's been a blast, and while not conservation, I believe what is effectively a littering PSA to be a worthy output of my time ha.<p>You can also click on many trees to see what they are, as most are from the Philly Tree Inventory (though more are added to fill out forest areas for style reasons).</p>

<p>to me it is just market pressure to exploit the high stress on laborers atm. the level of uncertainty today is only a problem if you don't have a ton of existing capital, which everyone in charge does. so they are insulated and can treat people poorly without repercussions. in a market that prefers short term profits, they will then do this in order to make more money right now.<p>companies must do this, 'cause if they don't then their competition will (i.e. the pressure)<p>of course, we can collectively decide to equally value labor and profit, as a symbiotic relationship that incentivizes long term prosperity. but where's the memes in that</p>

<p>We, consumers online, are sliced and diced on every single dimension possible in order to optimize our clicks for another penny.<p>As a side benefit, when you do this enough, the pendulum that goes over the middle line for any of these arbitrary-but-improves-clicks division builds momentum until it hits the extremes. On either side-- it doesn't matter, cause it will swing back just as hard, again and again.<p>As a side benefit the back and forth of the pendulum is very distracting to the public so we do not pay attention to who is pushing it. Billions of collective hours spent fighting with no progress except for the wallets of rich ppl.<p>It almost feels like a conspiracy but I think it's just the direct, natural result of the vice driven economy we have these days</p>

<p>I agree, I think this is a longer way to say what I was feeling. It's a rigamarole by people with too much money. If they had less money, they wouldn't be able to do it. So at the end of the day the root cause to me is the inequality. it allows special treatment and the ability to manipulate our daily life (through social apps, news, etc) in a way that they are completely insulated from, feeling no pain whatsoever. Huge policy failure to let so few people have so much influence</p>
