awesome! suiko2 is one of my favorites out of the entire series. I've played 3 and 4 but sadly not 5. I'm currently one boss away from completing Suikoden Tierkreis - for the DS. It's a great series, and I fully recommend getting your hands on the second one ASAP.
I loved 3, 4 was ok, and 5 was pretty good too. I wish I could get a copy of 2 that wasn’t $200, haha
