Seeing Xenoblade several times mention makes me cry on the inside. Sure it's not for everyone, but I spent way too much of my own time playing it. Soon I'll go for round 2 and 100% it. But I liked the battle system. Like someone mentioned, felt it was a better system than FFXII had.
Anyway, my pick would probably be Endless Ocean. I was looking forward to it. And don't get me wrong, I love the exploration part. But I hate the caged in atmosphere. Go in one area, can only explore that area. Gotta worry about air. Yeah I know we have to worry about air in real life. That's why I'd prefer not to worry about it in a game. I just want to explore. And maybe scare myself running into a whale or something.
The missions and stuff on it where pretty lame and I hated them. And I just felt like the whole thing was kind of clunky. It was a disappointment. But I tended to stay away from games that were bad, looked bad, or really had bad reviews for good reasons. I don't like to give companies wanting free money any.
