I try to return to 3 every so often, because it’s genuinely to this day one of the most beautiful games I’ve played, especially with full RT features enabled, but I never get too far before I just sort of run out of energy to try anymore.
First two are great, though I mostly ignored the exp systems and upgrades, outside of tombs. Some of the puzzles in the optional tombs were really fun, I heard there were some great ones later on in 3 too.
Idk about this, but the Mario 64 decompile was recompiled to run on my Anbernic 353 at 60fps, runs amazing. So I think it should be at least theoretically possible.
