I picked up Xillia today. I'm not far, but I'm really enjoying it.
I'm very glad to see the weakness system scaled back compared to Graces, that game went overboard on the amount of attack types. There are some little things that are nice too, like characters jumping off from the top of a ladder, camera control, and they finally added a map.
I also like having TP back so I can use healing artes outside of battle. :/
I like the mix of AC and TP. AC is much better for the combat system, but it just feels strange to me to have an RPG without a magic meter to manage.
This is also the first time I've bothered playing more than one character in a Tales game. I've been switching between Jude, Alvin, and Milla constantly, even in the middle of a fight. Linking is fun too.
I don't really have any complaints right now other than not having a side step.
