Lost Odyssey is the best JRPG on 360. I recommend that you play it last. The other JRPG's wont seem near as good after you play Lost Odyssey. I personally wasn't big on Eternal Sonata. Its short, linear, and has a poor story. The graphics and the battle system are excellent however. Blue Dragon starts off slow. It doesn't really pick up until the second disc, but the Shadow customization really makes the game fun. It is a bit on the easy side, so you'd probably want to download the free DLC that allows you to up the difficulty. Mass Effect is my favorite 360 game by far, but its a WRPG. So I'm not sure if its what you are looking for.
