I have to say that almost all of the minigames in Danganronpa 2 were either so easy it was just a pointless waste of time or just a really infuriating way of your character figuring out some of the most basic things imaginable. From what I've played of Danganronpa V3 its improved on them massively, but for 2 specifically I would have lost no positive experience from the game if they'd all been removed completely.
