My favourite Tales game so far (I've only played 4.5...haha) is Tales of the Abyss. I think the characters were not only extremely easy to connect to and sympathize with but the storyline of the game was stunning. I think the entire concept of it was amazing and I've only played it once because once I beat it I let my boyfriend borrow it, and he gave it back early in 2013 but I was just busy with school and work that I never got around to playing it again.

I really should get on that...considering I've played Graces twice and Xillia I'm on my second run too...
