What I want to finally happen in gaming is interactive environments. Having everything to be destructible is a good start. Have you played Noita?
Larian likes to create a “playground” type of experience, good physics engine and destructible environments would enhance that experience.
Total absence of loading screens. Once you load into the game, that’s it. Dungeon Siege did this in 2002. After finishing the game, I ran back from the final boss chamber to the starting village without any loads.
Day and Night cycle, dynamic weather.
More class - specific, stat - specific progression paths.Disco Elysium style. If not that, then drastically different choices and consequences between good and evil.
Can we finally get rid of clipping and get proper physics for character equipment? Not a single game in history has that yet.
