My son and I powered through the rest of Toy Story 3 before his bedtime tonight for the.
The game itself is a lot of fun and is actually a really cool kids game, but the PS3 version suffers from some terrible load times that rendered it virtually unplayable at points. I don't know how it compares with the 360 version, but considering loadtimes are usually faster on 360, I'm going to assume it handles it a little bit better.
Still. Onto something else. Might take him shopping tomorrow to find a new game for us to play.
