Beat 'em up. Slice 'em up. Win. Best martial arts simulator. No joke.

Everyone should give this one a try. As the most popular MOBA on Steam, Dota 2 has already proven it's worth and glory.

Not everyone likes it, but it is surely a version that should be bought as a new player to Dark Souls II. Dark Souls, ftw.

We can all be zombie-killing machines if we want to, and this game teaches us how.

Be creative. Do whatever !

Amazing war simulator. Fun to play with and without friends. (More of a chance to die without a group in my case... -investigatorRarity)

Space Ninjas.

Good game overall. Much like TF2, lots of people play it, and many people find it very fun. It is also by Valve.

Fun. Everyone plays it, unless they don't. Simple enough.
