Thought this was gonna be a sequel to Magic The Gathering before I clicked.

Why? Genuinely interested.

I wanted to check it out, but it's not preview-able anywhere, only for sale.

This won't matter. AI will be able to build the game from video of gameplay.

Without decompilation, it's impossible to say that you've experienced every aspect of a game. So AI will be able to build something that approximates part of the game from video of gameplay, but it will not be able to completely build the game with reliable consistency.

Streaming won't stop it, just have the AI play the game and do every possible thing.

Every possible thing! We can't even enumerate every possible thing in chess with a compact set of rules let alone every possible thing in something like Red Dead Redemption with unbounded complexity. "Thing" is not "what happens when you shoot an enemy". "Thing" is "what happens when you shoot this particular enemy in this particular place at this particular in-game time and this particular not-in-game time after doing this particular long sequence of other very particular things".

That's what the issue tracker is for. If someone notices a subtle difference and they want it added they'll file an issue. If nobody notices the untested space it doesn't matter.

Maybe we should start with something easy and clone Nethack by just playing it through..

Astra Max can do 12%: https://balrogai.com/

Though after improving the harness it can fare better, but still no completion: https://roger-creus.github.io/blog/astra-craftax-nethack/

If anybody's paycheck depends on "AI could never..." I suggest exploring other skills.

Good luck doing "every possible thing" in Minecraft or Factorio.

No need for residential raids. You know where the person is. Wait outside. Hostages? Wait out of sight. Eventually they come out.

I bet this will be as successful as Microsoft Bob.

My guess is absolutely nobody on the team that made this is even old enough to remember Microsoft Bob.

More specifically:

The thief valued the gain of the crime more than the risk of the crime.

Cost, not price.
