in my opinion
suikoden is pretty medicore. i've only played 3,4,and 5 and out of those i only finished suikoden 4 and it was the one i enjoyed most. 3 and 5 lost my interest before the end but 3 kept my interest longer. however i get the feeling i would of enjoyed suikoden 5 more had i played 1 and 2. another thing about suikoden 5. its not that the graphics are bad but when the same company puts out stuff like metal gear solid and zone of enders is kinda disapointing.
just for reference:
i lost interest in suikoden 3 when
the three characters meet up to fight a red dragon or somethin
i lost interest in suikoden 5 when
