Home of THE funniest workshop submissions on steam, this co-op zombie apocalypse simulator is quite possibly the best game to play with friends.

A great TDM/Co-op hat simulator that has a class for every type of playstyle. Workshop support allows some of the most impressive creations on steam.

A great game to play alone or with friends. Civ 5 lets you change history in whatever image you desire.

Has everything great about Arma 2 with a ton of added features. An extensive modding community and workshop support will keep this game alive for years.

The birthplace of DayZ. This game has everything you need to wage war with, or against your friends.

A game of twitch reactions and weapon camos. Need I say more?

It has "mod" in the name for a reason. There's an infinite amount of things to do and is a great game to play with friends.

It's still missing some features from the mod, but worth it if you put the time in. P.S. Don't get attached to your loot, you are going to die (a lot).

A game full of possibilities and unlimited potential. The learning curve can throw a couple people off this game, but practice makes perfect.

One of the best cooperative experiences I've seen in years. Yes, it has it's ups and downs, but cooking meth with your friends is always fun.
