I love GTAV so much, it's the most real single player world I've ever experienced. I once rear-ended an NPC because they suddenly stopped in the middle of the street. I got out of my car (because it's GTA and you have to shoot everyone, duh) I saw the NPC had stopped because he hit a cat with his car! I'd be lying if I said OpenAI Universe / GTAV wasn't one of the primary drivers in me trying to learn ML. Anyone know what kind of hardware I will need to play with this? The AMI page on github mentions an AWS g2.2xlarge (iirc a GTX 1060 is slightly better than this?). And it seems like GTA is actually running on a different system you use VNC to share the screen/input? Any estimates about whether a 1060 or 1080 on a beefy gaming PC could handle both at once?

It's technically possible to run everything on one Windows machine (using VNC loopback mode), however we expect most people to run ML on Linux / Mac so that is the best supported configuration. Before Universe, I ran a modified version of Caffe in Windows along with the game on a GTX 980 and there were more than enough GPU resources for that. Running ML / ROS / other self-driving software in Linux is much more ideal though.

  Thanks for this info. My gaming PC has a 7950, so I'd need to buy a Nvidia card anyways to do this. I was hoping to avoid the need to put together a second PC for ML, but I think I have enough spare parts lying around that I could do it cheaply, and I believe you about Linux being ideal over Windows. Sounds like a 1060 should be a good start for me to play with Universe then.

Hmpth. Conversely, while playing GTAV in completely innocent explore-the-world mode, I accidentally bumped a police boat with my jetski. Apparently this warranted being shot in the head. Most reviews I've read actually complain that GTAV is a step back in realism from GTA4 (for example, body-part specific injuries were dropped), but let's not beat about the bush - no GTA deserves the title of "realistic", because as you say "it's GTA and you have to shoot everyone, duh". They're made to feel realistic, but in fact they powerfully reward violence and punish being law-abiding, in precisely the opposite way that the real world does.

  > no GTA deserves the title of "realistic" depends on what you prioritize to mean "realistic." I think most people would agree that the world of GTA V (and IV) is incredibly realistic by video game standards, to the degree that it's the obvious choice for this AI project.

    That is right in everything, but shooting and taking damage, which is mostly irrelevant for driving AI.

      Well, if it had imported the body-part damage bits from GTAIV (which it didn't), at least those are easily fixed by tweaking some data points.

  Of particular relevance here, another aspect where GTA V is supposed to be less realistic than IV is driving physics (i.e. handling). I wonder if OpenAI is using one of the mods designed to address that.

  I enjoyed GTA V because it was so hilariously over the top. It didn't try to be realistic. The whole point is that the police response is always massively disproportionate to the crime. It's a pastiche of society, everything is exaggerated: they have a legalize medicinal cocaine campaign, you can buy supercars online, rocket launchers and machine guns at your local gun shop, you can launch your car at 100 miles an hour of the edge of the highway and survive. They even reference the outrageousness of it in a scene where Michael goes to the therapist and comments that he may have even killed someone on the way there.

I don't remember if GTA V had this same feature as GTA IV, but I remember being impressed in GTA IV by the cell phone interference through the radio when you had an incoming call and the radio was playing. I just absolutely loved the attention to detail that game had. It was truly the small things that added up that made you want to figure out what other details they put in the game.
