I asked what he specifically liked.....this was my reply:
An expansive story, lots of playable characters. I do not know, epicness. I do not know how to explain it.
It was just the greatest gaming experience on the PS2. I really got to know every character, I replayed Suikoden 3 several times over. And replayed 4 and 5 almost as many times.
As you progressed in the game your castle became bigger and more populated, like it was a town instead of a rundown broken castle. Characters culd team up for some wicked combo attacks and the magic system was unique in that almost every character could use the same rune if you wanted them too.
