I am hoping ModNation Racers will become something of a fine wine. Sure it is enjoyable straight off the bat, but give it time, as it ages, and it will become a much better and richer experience, as more and more creators add their own tracks into the game via its powerful creation system.
Extensive character; kart and track creation; Longevity in both on and offline modes; Challenging campaign and gameplay
Steep difficulty curve later on is frustrating; Kart performance tweaking would of been good; Long loading times
