I joked about Mario Kart World being emulatable before New Year but I guess jokes are real now. What was the timeline on PS5 emulation again? Booting into title screen in the summer?
(nxnative is apparently a Switch 1 ARM translation layer for macs and the developer seems to have a legit reputation)
The real remaining filter will remain playtesting. Not because you can't have a bot jump at every single wall in your game 1000 times per second to look for bugs, but because good ideas and iterating through the development process can't be skipped. The difference between slop and a game made with AI tooling is and will remain "did the developer actually have an idea beyond copying the current thing and did they playtest it to make it fun".
