Started playing Vesperia today. I'm not very far at all. I just got out of the initial castle, so these are most of these are the earliest of early impressions, but I really like it so far. Yuri is a really cool main character. He's a ton of fun. It's really nice to see a decent male lead, given the only leads I've seen so far are the boring Jude and the absolutely horrendous Asbel. While I don't like the art style quite as much as Xillia, it's a neat middle ground between the darker, serious style of that game and the super light and colorful Graces art.
On the negative end, the game definitely is showing its age a bit. The areas feel really small and confined. It's probably not as confined feeling as Graces, but its a far cry from how big a lot of Xillia locations feel. Also, I think most of the fonts in the game look dated and kind of ugly. So far, the battle system feels slow and disjointed, but I imagine that's mostly because it's so early on and it'll speed up once the game gets going.
One last thing, does the game really not have an AC equivalent? How do you expand your basic chains? That was one of the biggest surprises seeing the battle system for the first time.
