Grandia II is awesome. And it's for Playstation 2 and Dreamcast I believe. I liked Roan. There is also another Grandia game out as well. Grandia Xtreme is for PS2 and it's got a very different storyline but the battle system and such are the same. Also the first Grandia is a bit different than II and Xtreme but it's a good game as well. The first one is on Playstation.

Anyways, the reasons I liked Grandia II were that the characters were funny and the story was interesting. Also the battle system is fun.
