Battletoads

The Good
It's a funny game. The world of the game is very bizarre, but will make you laugh (if you're not pulling your hair out). The gameplay is also varied such that each level offers a different experience with different challenges, thus preventing the game from ever becoming repetitive.

The Bad
The worst part about Battletoads is that it's so very hard (and when you DO beat it after a very long, difficult time, the ending is very short and entirely unrewarding). Some of the levels are just too difficult (Volkmyre's Inferno, ahem). Also, clinger winger is impossible with 2 players (literally) because of a glitch that automatically kills the second player if you ever make it there (it's the 2nd to last level).

The Bottom Line
This a game that has a lot of good things going for it. It's fun to play for the most part, and it's quite a unique experience, with each level offering something new. Playing 2 player is always good for a laugh or a fight, since you can hit your friend on purpose or accidentally.
