haven't palyed Suikoden V but I wanna speak up for DQVIII. It's one of the best RPG's I've played in a long time, the storyline is probably longer than most games you'll play, its characters are unique and interesting, and there's a huge amount of crap to do on the side.

The world design in this game is almost unprecedented. The music is breathtaking and the graphics are unbelievable. Like really, unbelievable. I'm the biggest hater of cell-shaded games but I think it's one of the most graphically impressive console games I've owned. Check it out.
