I remember playing Suikoden IV for the PS2, a really good Japanese RPG. I really loved the character intensive story driven rpg style of this game.
Something very unique to this game is the number of characters which you will encounter in the storyline. It surely boasts a huge number of unique characters which many rpg games would envy of. It was a really good fun to level up all those characters and play through the storyline. I hope they get the same experience to the handheld. I'm really looking forward to playing this on the DS. I really hope this releases by early next year (something to look up to early next year!), but no release date on this yet :(
