Game got a bad rap on release, but it will definitely become one of your 70% metacritic favorites that you won't admit to love. Put points into Stealth!

Better than GTA anything. Compelling narative, kickass Batman-esque combat, and open world driving that is actually fun. 10/10, would play again.

Call of Juarez 1, Bound in Blood, and Gunslinger are all AMAZING games. Gunslinger is a western cooridor shooter at heart, and a blast to play through.

The only multiplayer air combat game you need installed. Is free and can be played forever without grinding or spending a dime. Supports Oculus Rift.

2 games in 1, RO2/Rising Storm allows you to join one server and switch from german to japanese WWII front depending on selected map. Extremely tactical

You've never played a game like this. Perfectly polished multiplayer medieval FPS. It's a blast to play, and is updated with new stuff every month.

Perfect middle ground between hardcore sim and fast action FPS. More tactical than CSGO, but not burdening to newbies. Less intimidating than RO2.

Mafia II is the sequel to one of the best PC gamers ever, and it doesn't disappoint. Extremely strong third person shooting mixed with open driving.
