-Oh, you said 2035? Unless neural interfaces break into the mainstream in the next ten years gaming probably won't look that different from today. Nintendo could play it safe with a ~Switch 3 but just as likely won't be able to resist trying to reinvent the wheel again. Xbox may become third party in all but name if recent trends continue. Sony will have the PS6 and 7 to fall back on when they all but inevitably don't give their side project(s) the support they need to really succeed.
As for the games themselves, real time ray and path tracing will be mature enough to make raster obsolete for big budget titles. Hopefully physics sims stop taking a back seat to other tech. The biggest differences, like it or not, will come from developments and integrations of AI. Faces could be deepfaked for even more realism, subtle animation behaviors could be improvised on the fly, automatic lip syncing will continue to improve, npc's could ad lib lines and responses to the player, ChatGPT and the like could become a crutch for programmers and other developers like it's becoming for students now. AI is developing so fast it's hard to predict where it will be ten years from now. If you'd told me five years ago where it would be today I wouldn't have believed you.
