How Good is Metal Gear Online?

[raginranger]

Hello,

I've been trying to sift through all the information on MGS4, but most everything I read focuses on the single-player part of the game which I hear is amazing. However, I don't buy many games and the ones I like most are usually online multiplayer. This brings me to my question, exactly how good/fun/long lasting is the metal gear online part of this game? Is the community large? Is the set up good, not much lag, etc?

I would like to get this game, but don't really want to drop $60 just for a single player game. Sounds lame, but I need good multiplayer to plunk down the big cash for.

Thanks in advance.
