I recently purchased a Playstation 3 and was sad to realize that MarioKart (my favorite game) is a Nintendo brand game and not produced for the Playstation. After researching a bit I found this game, Sonic Sega All Star Racing, and decided to give it a try. It is seriously the only the game I play! (My husband plays the other games :) The graphics are incredible! You can play split screen with up to 3 additional players which is really fun but can be a bit confusing on some levels because of the vivid colors and all the moving graphics in the background...but that hasn't kept me from racing everyone I possibly can! The characters you can be are really neat, a step back in time kind of...such choices as Sonic, Knuckles, Tails, Dr. Eggman, and even the Street Fighter guys!! There are a multitude of new drivers and courses, along with music, that you can purchase from the game store using the money you earn while racing :) The money isn't hard to earn either so it doesn't become frustrating at all when you are trying to work up to buying something new, you earn about 2,000 credits on average per race with new drivers and courses ranging in cost from around 4,000-35,000 credits. The game offers a variety of racing types for single player so you won't get bored easily, you can do time trials, grand prix challenges, missions, and single races...all of which earn you points and trophies. When playing with more than one player you have a choice of different race types as well, althou.
