It is amazing for playing with a buddy, or *shock* your significant other. Cat loves this game.
It's basically a side scrolling RPG, where up to 4 players can be little knights. You gain levels, upgrade their stats and magic, get new items, and all sorts of generic fantasy stuff. There is plenty of humorous references, and the big boss battles are the best part about the game, by far. There was an arcade game involved King Arthur that was very similar to this game, only not as well done.
