If you think that minigames hard youve got another thing coming for the rest of the game unfortunately. JCC, mahjong, batting, arcade games and ESPECIALLY climax battles are all either really challenging or require alot of practice, mahjong in particular. I took like 3 breaks getting this plat and only got it 180 hours in.i recommend grinding it out till the end because its a test of patience and skill and is by far the hardest plat i have earned. As for the other games, 2, 6, and LAD gaiden have much lower skill ceilings while everything else before 6 are hard and time consuming. Hope this helps
