My problem with JRPGs is that almost all of them are turn-based.
I find that boring and tedious, tried to play a few and always had to fight falling asleep of boredom.
It's not the only problem I have with them, but is the main one.
I also think that they all look the same, play the same and have the same story.
I gave them several chances, there is no chance I'll ever play one again.
