Sometimes, playing it turns into little more than an exercise in frustration. ModNation Racers, Sony's upcoming racing game, may not make a big deal about going after Nintendo's best-selling franchise, but there is some competition going on. We've had a preview build of the PSP game for a while now, and yes... this is a big leap forward for the kart-racing genre."
