Glory of Hercules was pretty boring to me, at least by the end where you fight these enemies that take forever to die (like you actually have to pay attention in battle to make sure you overkill the right enemies). It's not a bad game, it's just very tiring after a while.

Besides auto-battle in Suikoden II, it is just naturally easier than a lot of other games. You don't have to level grind at all, the game is paced well so that you don't have to do any extra battling.
