I'm curious - why is it that people say online gaming is so much better on the xbox because there are more people online? You can't play with more than like 32 people (depending on the game) at the same time anyways, so who cares if there are thousands or millions playing at the same time as you?
I've done quite a lot of online gaming on the PS3 (Warhawk, Resistance, Rainbow6), and frankly, there have always been PLENTY of servers/games to choose from, loaded with people. NOT ONCE was there a shortage of servers/players.
Maybe there are even more people on xbox live, but I just don't see the benefit of it.
You're not saying that to enjoy an online system you online need 32 people playing worldwide?
There are still thousands of people Mario Kart DS, but it doesn't make match finding easy as there are so many parameters for matches that can cut thousands of people down to just a handful. Ping latency, game options all come into account.
More is better, don't let Sony tell you any different
