I like how they spiced up the matches by limiting what you can do. The first beta gave us Deathmatch and Plunder. Beta 2 introduced matches where you can only use pistols and snipers, have 1 life to live, or use RPG's only. There are also different modes for cooperative play. I tried it out by myself and didn't find it enjoyable. Maybe it will be different if my friends were on.
A note to all who play shooters with inverted, or flipped, controls. I performed horrible in the first few games because I only inverted my AIM view. I didn't realize there were two places to invert in the options, AIM and Look. I think this is the only game I have every played that had 2 forms of inversion.
One of the greatest features Halo introduced was the ability to view your stats on a website. Kudos to Naughty Dog for incorporating this into Uncharted. I can view the wins, loses, kill death ratio, etc. at www.naughtydog.com/stats/meatwad101010.
Finally, a PS3 game worth getting.
