Suikoden is one of my all time favorite RPGs. I can still play it over and over again. I probably won't buy it for PS3, though, since I still have the original disc and can play that instead.
For whatever reason, I could never really get on board with Suiko2, though. I'm not really sure why. (This is after I finally decided to spend the $80 or whatever to get it off eBay, heh.)
