Recommend a game... win a prize 2 :D

Warhammer: Wrath of Heroes

If you like Diablo types, I highly recommend Path of Exile (http://www.pathofexile.com/) and there's Drakensang Online (http://www.drakensang.com/). If you like MOBA types, there's DOTA 2 (http://blog.dota2.com/) and SMITE (https://account.hirezstudios.com/smitegame/). If you like MMOs of any type, there's WarZ (http://www.thewarz.com/), Ultima Forever (http://ultimaforever.com/), Phantasy Star Online 2 (http://www.pso2.com/us/), Warhammer: Wrath of Heroes [they basically took the battlegrounds out of Warhammer Online and made it F2P] (http://wrathofheroes.warhammeronline.com/intro/index), and Darkblood (http://darkblood.outspark.com/).

Most of these are playable now, but there are a few like Phantasy Star Online 2 (beta is available in Japan and you can sign up through the Japanese website). I only list some of the non-playable ones so you can sign up now if you're interested. Anyways, sorry for the novel.

Dead space 2. One of my fav horror game of all time and even now it is still the most enjoyable for me. =D

Zombie Grinder, it is non-steam (it's for desura, or DRM free) its a sombie survivor game with retro graphics, it is a funny game!

Project Zomboid, Towns, Brick-Force, 3079,

Raiderz ( Beta will start at August 8 ) , Ends of Nations , Smite , FireFall , Ravage ( Stema game in beta ) , ShootManyRobots : Arena Kings , etc.

Got to recommend , Pay-day or Crysis Warhead! NICE STORY , NICE MULTIPLAYER!

smite

3079, it's in alpha, you can get it here 3079.phr00t.com

Also a mod called No More Room In Hell. It's available if you have Half Life 2 ( Possible other Valve games ) http://www.nomoreroominhell.com/ (beta or alpha)

there's this really fun game called kerbal space program or ksp for short. You build insane rockets in hope to land on the mun. yes I said mun thats what they call it in the game. http://kerbalspaceprogram.com/ You can preorder for 15 dollars but there's a a playable demo that's not really a demo at all. Its just a older version of the game.

The Dream Machine! Just love.

Try out this. It's a sandbox zombie survival game ! One of the best indie games since minecraft imo

RaiderZ... Thanks for the chance! xD

Stronghold Kingdoms
The Settlers Online

End of Nations just entered closed beta phase this weekend. It's amazing if you're an RTS fan.

Edit: I would also suggest 99 levels to Hell if you'er looking for a more indie sort of game.
