Uncharted 2 is brilliant online. But it can't touch MW2. I even find MW1 to be more to my liking online. But I am a shooter purist and don't really like 3rd person games. Uncharted however plays very well even though I don't like the damage model (even on crushing). It takes too many hits to kill someone.
But apart from MW it is one of the best online games we have on the Playstation 3.
Still not getting any lag at all. I can't see how some are having problems and others aren't. Very strange, unless it has something to do with connecting with the US on matches.
But then I have no problems on any games apart from BF 1943 (disconnects after 24 mins) and COD WAW (doesn't even connect to friends).
I know this post is a year old now but I honestly don't know what anyone is talking about. It's never laggy for me unless the game host has a bad connection. I find a game almost instantly everytime. It has crashed on me a few times but that is down to my PS3 needing resetting. Occasionally it will take a few times to actually log into multiplayer but and pops up with "syncing error" or something but after a few tries it logs me on which I think is down to multiple logins on the server at the same time. All the problems I've had are by other people's connection or my PS3. As for the amount of people playing being between "12,000 and 15,000" is absurd. There are about 70,000 on average a day which is on par with modern warfare. And there is a global leaderboard aswell which compares money and kills and wins and such.
This might be outdated and it might be because they released a patch or something but I had no problems that I could blame on the game.
