I was sitting here working on my laptop, with my music playing on super-shuffle (I've got a monsterous MP3 collection) when my computer descided to play the end-theme to Xenogears (PSx game). It actually brought a spot of moisture to my eyes and a deeply nostalgic feeling before I even realized what I was listening to. Cross your fingers and hope that SquareEnix and Sony will allow this game to be ported to the PSP. It's truly one of the crown jewels of the RPG game genre. If you havn't played it yet, and own a PS2/PS3/or PC (using Bleem!), and if you like RPGs, then you owe it to yourself to get this game. The combat system was a little clunky, but the story was thick, juicy, and in quantity. To this day, this is the only game I've ever played that can summon up such powerful emotions.
You can pick up Xenogears for $15-30 from ebay.
