Very quickly repetitive. Handing the user all the monster combos up-front takes the fun of discovery out of it. Seems to be no reaction of the outside world to your group. At Arena Level 7, with 4 red monsters I fought 1 Green & 1 Yellow... and pwned them hard! No way to combine 2 reds, but I'm allowed to put them in the combo machine. No way to "train" specific monsters to get better. Very pretty, but very dull.
