I've been playing the review copy of this and to be honest, I'm underwhelmed. Creating monsters thus far doesn't really feel creative, rewarding, or fun.
The game is plagued with constant loading screens, and some really tedious decisions (healing your monster after each battle), and the mini-games are repetitious and gimmicky. The one thing I hoped would hold it up was the combat, but even that proves quite easy and boring after a number of battles. Perhaps the difficulty picks up later in the game making everything more tolerable, but I'm currently leaning towards about a 6.
