Daibijin
Fanservice and giant monster mania collide to produce this game. Buy the game for the novelty of it. It is quite good.

The Daibijin
Once you get a hang of the controls, this is a pretty fun game. It's very short, but with all the unlockable bikinis, you'll have to play through it a few times to get everything. It may not be the greatest game ever, but with the mix of gameplay and just sheer strangeness, The Daibijin makes for a fun game to show your friends something different.
