Persona Series

While I've played other MegaTen games, I've yet to play any of the Personas because 1-3 are freaking hard to find (and 1 is expensive as all get out) and the only copy of 4 I ever had didn't work. As soon as I can figure out how to get my PSX emulator to work I'll play P2 and I plan on getting a PSP soon to get P1 and P3P as well as some other games.

I do have a ton of music from the series already though. The Battle for Everyone's Souls is probably one of the best boss battle themes I've heard.
