Well I'm 20 hours into it and I think I'm almost done. I like how they brought back a lot of Suikoden 2 characters like Georg Prime, Jeane, Killey, and Viki(of course).
The only thing I really don't like about this game is the major battles. Some times you have a sea battle and land battle at the same time, so it gets really hard to manage all your troops.
Overall I rate it: Suikoden 1 < Suikoden 3 < Suikoden 5 < Suikoden 2
