We've played every version of Godzilla on every console. Godzilla Unleashed for the Wii is fun like always but not something you just can't live without. This game is actually more fun on the Nintendo DS than the Wii. The Wii remote just doesn't work that well on this game. The movements of the characters are slow to respond and if you don't move the remote just right you don't get the intended move.
This is definitely a rental game and has some fun value in it but after a few hours you'll be ready to send it back.
