Most fun multiplayer?

I know that GTA IV is the most played XBL title (for the week of 5/5 at least) but which do you guys think is most fun?I just started playing COD4 after a solid 2 months away from it. I went 18-7 my first match and 32-9 for my second match. I had no idea what I was doing (too unfamiliar with the controls, hitting right stick in for crouch, ''A'' for sprint, right bumper or ''B'' for reload because of all the GTAIV and Gears I had been playing). I have forgotten how much more fun I had playing COD4 online than GTAIV online. GTA is great, but COD4 will always hold the top place for me.Most fun multiplayer?
I own all the games you mentioned, and my favs are Vegas2, Team Fortress2, GRAW2 and COD4Most fun multiplayer?
Poor GTAIV.
CoD 4 is WAY over rated. It gets boring before the first prestige.Gears on the other hand lasted me a solid 7 months of gameplay with 2-3 hours a day of playing.

It's consistently fun and exciting, especially when you're the last one left on your team.COD4 is still fun for me (I did 1 round of presitge and stopped). The challenges are cool and I'm tyring to get the golden guns right now. I guess I shouldn't have stopped playing for so long. I guess I like this game because it's so easy to get kills :D
GTA IV for the sheer amount of play options. COD4 however is definitely the best online FPS, bar none.As an ''other'', I'd like to nominate Splinter Cell: Double Agent. No one seemed to like it, but I could never understand why. Online was so damn fun and original, unique.
Frontlines: Fuel of War.

Halo 3 and GoW

Halo 3 is my favourite. GoW has terrible bullet lag so it was very frustrating sometimes.

Gears of War is the most fun multiplayer game on Xbox 360.:)
i would say i play halo 3 the most or cod4. gta 4 is alright i just do racing.
Gears of war for me. I mean i've had the game since jan. 2007 and i still play it till this day. Thats how addicting the online was to me. COD4 was good for about 1 month got bored. Halo 3 was good for about a month got bored. Gta4 lasted me a week before i got bored. Rainbow2 i actually enjoy and play it as well but its no where near as good as Gears of War IMO.
I have the most fun with Halo 3, especially in customs games, GTA4 would have to be next, Gears of War, and COD4.
Id have to go with Call Of Duty 4, the lvling and gun system is fun. But i did slow down playing after first prestige. :(
