I'm really impressed by this, it's a gigantic technical leap that the series always desperately needed. Black & White were a start but they were nowhere near this level. A third-person view instead of an overhead/fixed camera view is very different too.
I'll be choosing Froakie as my starter, because noone seems to like him
and he's the least cutesy one.
Just judging from the two legendaries at this point I'll probably get Y version since I like that one more. Though that's due to change.
