No, I also only tried some to see if they are running.
I'm thinking more of the technical capability. I tested some Chinese browser game that played like an old GTA and it worked decently well on my iPhone.
Evidently the tools are good enough now.
I believe the issue is that there's a lot of people who just release slop. Both for games and regular software.
To build a decent product you need to invest months into testing and refining. Clearly many skip this in order to ship barely working garbage.
For the capabilities of eg. Opus 5.5 to diffuse into actual products rather than just demos, it's going to take some months.
I'm sure some readers are thinking that I'm just moving the goalposts into the future here, but it's the truth. For the games that were made with AI and which already are making money, I found that many are projects started already last year.
I myself have been working on a commercial mobile app for the last six months, targeting a release this week.
Building a good product still takes time.
