Idea:
idk if your planning on this or if in the game Bc I have not played to far in
But what if later on in the tech tree you could unlock the ability to do multiple genres at once, like for the first upgrade you would unlock two at once and then the second one could be 3 at once. once you have multiple genres you can select the amount that you have unlocked (2-3)
and a slider would pop up and would chose how to evenly divide 100% into the genres you selected.
EXMP (50%ROLE PLAY-50%ACTION)
or (35% Adventure-35% Puzzle-30 Racing)
-Also more genres
