First post here, because I was looking around online for a place to discuss the beta. Seems like a good community.
One great thing about Uncharted 2 MP that hasn't been mentioned here - and this is perhaps my favorite part of the beta - is how it matches you with similar players. Most games match you aganist people who have the same experience level, and this one does too at first, but if you aren't very good and get the crap kicked out of you, the next game it will match you up with people of a lower experience level. At first I didn't like having to get matched with new people each game, but I've grown to love it because it keeps me from getting too frustrated. It makes the games more even, and therefore more fun. One of my biggest complaints with playing Call of Duty 4 is late at night the multiplayer is filled with people who are ridiculously good (and likely play the game all day long, every day), and I get tired of getting the crap kicked out of me and turn it off. But that's not a problem with Uncharted 2. It's good times.
