as for me, i hope texture uv's stays the same since they works 100% well,
even idk maybe 100% no nesessary fix normal maps and chrome, maybe add decapped head texture, or fractured/dismembered joints single texture, also will be cool make floor texture (ground) much larger even with same resolution, also maybe game menu whole window background texture customisable,
also main thing - do a full game video guide maybe integrated to the game,
cuz lots of beginners think this gan=me too hard - but it will be fixed if make good integrated to game video-guide.
also maybe switchable double head texture (not sure) - but it will let do 1 frame face animation.
custom folder textures protection maybe by any decoding, arhivation system (not sure its exists and possible)''''''
