my idea was of dynamic content. the 3D asset combinations are already in the game so you'd only need dynamic dialogue and expressions according to which repeated optional potions are picked, maybe tailored for adventurer archetype even.
also i'd like potion magnification. i was VERY disappointed when i lost the cowgirl bras because i could keep making the boobs bigger with them. i'd love to somehow use stronger and stronger BE potions even when not needed.
