Radiant Silvergun's final boss actually fits well with the context of the game.
And, since the game is now available on XBox Live, for those who have XBox 360's (I don't, but at least I have the Saturn version), the game is a great buy at 1200 points($15 I believe), as opposed to paying $100+ for the Saturn version.
