Yes and no.
Yes: For the reason that L4D is everything you ever wanted for multiplayer. Survive the zombie apocalypse... with your friends. The game seamelessly blends co-op action with gripping survival-horror, sure to keep you playing away into the night on your first go-through. It gets even better with versus mode, where you can be ifnfected. The only thing more satisfying than blasting a zombie off your friend is being that zombie when you jump on him.
No: L4D is a great game, but the community falls short. Wherever you go you can find people who let down the team, either by using glitches, not having a mic (Which I HIGHLY reccomend, or team-killing. The difficulty curve is a steep one at the higher levels, so unless you play at a high difficulty constantly, you're going to have a tough time getting teams together that are worth two shits.
I got it, and I have never regretted my choice. Its a ZOMBIE CO-OP SURVIVAL EXTRRRRRRRRRRAVAGANZA. make sure you bring a mic.
