To put it simply, Pac Man World 2 is an "OK" game.
Graphics- The graphics are great and the scenery of each level is different and it's not an eye-sore. However, the camera angles of the game are hard to play with at times when you can't change it (ex: There is a tree behind Pac Man but when he steps forward all you can see is the tree's leaves!!).
Gameplay- It's fun until it gets really hard after the 3rd or 4th level! This is a good game for gamers that have patience play the same level over and over. After you beat the game, you can play in the Pac Arcade and play the classic Pac Man games, (Ms. Pac Man, Pac Man ..etc) if you have enough tokens.
Sound- *Boing Boing*(the sound that Pac Man makes..haha). There are also sounds from the classic Pac games (ex: The same sound when you lose/die, when you collect pellets, etc.)
Overall, a good game to rent. If you like it buy it for the $20 (IMO it's not worth $50).
