It's fun -- I tried both of them..my sister-in-law helped me go through it on one of them together by IM. 
Both adults and kids can play these games, but you have to figure out some clues first to get to the end of the game!
WARNING: To play the game, try not to get Garfield scared (or you will lose points and then lose the game)!
