I've only played Suikoden 1, 3, and 5... mainly because I heard 4 wasn't very good, and I can't find 2 anywhere for a reasonable price. I have heard from a bunch of people that 2 is the best in the series, though, so I'm hoping for some kind of release on Playstation Network (like they did with Suikoden I).
My brother uses the account at times to play L4D, but he crashed his computer so it's most likely you'll be seeing me for a while.
See ya on the battlefield
