A delightful love note from Jack Black to Heavy Metal. At its core a sandbox action adventure game, but that is somewhat sidelined during the games second half, being replaced with an interesting, albeit less tactical, take on the real time strategy genre.
With a great soundtrack, a fun and interesting plot as well being funny at times, this game is definitely worth the price if you're a fan of some combination of Action Adventure RPGs, Heavy Metal and Jack Black. If you hate any of those aspects, give it a miss. You will find it overbearing.
