NOT TRUE! Splinter Cell is an AWSOME game online and just as addicting as socom can be. HOWEVER it never can seem to stay popular enough. I bet the splinter cell servers have no one on them now a days because people just lost interest in it because the popularity died.
I remember when Pandora Tomorrow was put online. That stayed popular all throughout that summer but once school started everyone stopped playing it and never went back to it.
I like BF2: MC because of the map layouts, and the lead to sniping in the game, I reccomend it for it's online play, but beware though, be prepared to play a whole lot of Backstab
Alos MGS: Subsistence is a must have too, not only because of online play, you get MGS: Snake Eater, & MG1 & MG2 all in a 2 disc package
