I was thinking about how having sprint mapped to L2 seemed familiar... Then I remembered Dead Space. Glad sprint isn't always on like in games like Uncharted. Makes it seem like you have more control over your character. I can't tell you how many times while playing U3 I've had Drake accidentally go into a full run, knocking into objects and flailing around, just because I put just a little too much pressure on the analog stick. Not to mention the constant tripping... It was a fantastic game, but that got annoying.
