I haven't played it online in a long time. Still have an open account with them. I checked last month and 2 servers are usually full. I'm not sure how many people can be on a server at 1 time. Maybe a 1,000. So there may or may not be more people on the 360 version. When the game's demo first came out all the servers were full and it was hard to log on. There were only a few servers up back then though, now there are 20 or something.
360 Pros: Achievements, voice chat, XBL integration (txt through XBL and MSN, see what your friends are doing), play with people across the world.
PC/PS2 Pros: Can migrate your account across both versions.
keyboards work on both versions for chatting.
