I voted for FFXIII (yeah that's right bitch), but only because Fallout: New Vegas isn't on there and I haven't finished Skyrim. I can't stomach most of the JRPGs on the market, I am a grown ass man and they just seem childish and ridiculous. FFXIII had problems, but it gets way too much hate specially when I hear the games people praise instead. I tried playing Tales of Vesperia after people kept telling me how amazing it was, and I was uncomfortable playing a game that I thought was clearly aimed at children. My intelligence was insulted with every conversation.
I don't have a Wii anymore, so I haven't played Xenoblade. If it's anything like what I just described, I probably wouldn't like it.
edit: The 2 FFXIII games should be seperate, they are very different.
