Like most successful, child friendly genres these days, LittleBigPlanet now has its own kart racing game. Here's the full demo from SDCC 2012:
Unfortunately, I was just being polite to the Sony rep. This game lacks the fun tenseness of good kart titles like Mario Kart, while more heinously lacking the spirit of LittleBigPlanet. The controls are sloppy, items are uninspired, and is generally boring.
I'm sorry, LittleBigPlanet, but this is one game you did not capture my heart. Instead, you stumbled into the same pool of mediocrity as Crash Bandicoot, Sonic, South Park, so many other great IPs. Maybe someone should find out why Mario Kart is so much fun before trying to make their own game in the same genre? And no, the secret isn't characters with big heads in tiny cars. Though that can't hurt.
