Yeah, I decided to try Gears 2 out. It's been pretty fun so far. I'm at the run-down facility/warehouse/whatever where that "semisentient" security system, Niles, is talking to you and you're shutting down all the security lasers.
Going inside that giant worm was pretty neat. I haven't seen that sort of idea explored in a game since Lord Jabu Jabu back in Ocarina of Time (one of the better parts of that game).
