It's frozen a couple times on my Xbox, once in the bottom of the ninth.
The game isn't bad once you get past the learning curves in terms of the hitting, pitching and fielding. I'm digging the idea of having to take a step and time the pitch before hitting (over pushing a button at the right time), and the new pitching mechanic isn't bad, though I'd wish the stamina would be worked over a little bit more. Starters shouldn't be losing 3 points for a fastball, and a middle/late reliever shouldn't have the gas of a starter.
Fielding, however, is a complete pain in the ass. If 2K is going to release a patch, I want that and the commentary fixed. Someone tell Jon Morgan that there wasn't a strike last year, and people did have more then no homers and RBIs.
