This version is a lot less fun than AQ Worlds. There's really nothing to do except for fight monsters over and over, which can get pretty boring after a while. It would just be nice if it were a bit more fun.
I've been on battleon since before Adventure Quest worlds came out and I am still really enjoying the game, enough to spend real life money on it, yeah there's not quite as much to do, but even mindlessly battling for a while can be very relaxing.
