There are a lot to choose from, but from what I understand, PS2 has a really nice collection of JRPGs. I am a fan of Final Fantasy X (only the gameplay really. I had the most fun at the end of the game doing sidequests and achieving stuff for completion). I also tried playing Makai Kingdom. While I really liked it at first, it became clear that the quirky mechanics of the game were often trying too hard to be "different". It is too much tedium for me. I realized how many ridiculously unnecessary stat considerations there are that I was extremely anxious the entire time I played the game. The way classes and their upgrades work is also incredibly terrible-- I simply am not willing to expend this much energy towards a game like this. Don't get me wrong, I like "complex" menu systems and all that great stuff but Makai Kingdom is trash. I may have really gotten into it if I were a good bit younger with more time on my hands.

I tried playing Disgaea and I got sidetracked before the first battle ended. That is not a testimony. I simply need to play it again at some point. I'm hoping it is a sensible version of Makai Kingdom.

And thanks everyone for the suggestions. I may find myself looking into Final Fantasy X-2, Persona games, Suikoden, and more.
