I just wanted to make sure this game gets a little attention. Is it the next best thing? No, but if you enjoyed Mario Kart back in the day, and don't own a Wii right now, this is the closest thing we have gotten in a long time. I played the demo, which is available for free on PSN, and loved it. I love kart racing games, I think mostly because they revert me back to my childhood, and I think this will do nicely to tide me over until ModNation Racers comes out in June!
I'm really looking forward to All-Stars Racing as well. The demo was terrific and reminded me of Crash Team Racing on the original Playstation. I also liked the drifting better than how it was presented in Mario Kart Wii.
Oh, and speaking of Modnation Racers, did you play any of the beta? It played it briefly and wasn't too terribly impressed with the controls and graphics. Looks the the strong point of it will be the user-created content... so it's my hope that the Sega one will be the definite kart game on the PS3. We'll see.
