They're not all that bad. There's a Lightning Speed Run one that's perfectly fine.but half the other's I just quit and skipped since I just could not be be bothered to deal with the RNG. Thie is someone who wasn't tyat bothered by FFX minigames where my primary annoyance were the poor controls of the chocobo itself.
You're only forced to play them once each, and even then you can skip them from the start menu, so if you just want to finish the game they're relatively painless. That said, they have one trophy each, and sadly even if you don't care about that there are completion rewards in the form of mirages.
Oh ok, thanks for the responses. I made myself grind those X mini-games for the Platinum. Fuck that lightning jumping lol, if it's anything close to that I might bow out.
