I was playing X-2 for a while and really enjoying it. I guess I didn't do enough sidequests in the first chapter, because as soon as I advanced to the second chapter the difficulty ramped up substantially and I hit a wall. As in, it was hard to even grind for EXP because random encounters in the second chapter were as tough as boss battles in the first chapter, and I was getting wiped every other battle. That was pretty discouraging and after a while I just put it down to focus on Wild ARMs 5 and Persona 3 FES instead. I guess I'll pick it up again after I finish those two.
