The Xbox360 would have to be Tales of Vesperia because the tales series is great. The PS3 I would choose Eternal Sonata because the mixture of fantasy and reality was a different twist on the RPG genre. I do not own a Wii so it would be really hard for me to pick a favorite on that system. I would have to say my favorite JRPG over all would have to be Eternal Sonata, I own it for both the Xbox and the PS3. The PS3 version was much better than the 360 one because of the changes made before the port. I also will try anything that NIS America puts out, even though some of their games are really odd their sense of humor is great.
