The successor to XCOM: Enemy Unknown is one of the best stratagy games of all time

A surprisingly engaging and fun experience, if you haven't played Harvest Moon I would recommend it greatly.

Mirrors Edge mixed with Dead Island, what more could you expect than a load of fun

Mechanically interesting and an engaging experience. SUPERHOT stands as one of the most interesting shooters of the past couple years.

The most immersive and complex military simulator out there

A tactical, dynamic 5v5 multiplayer shooter based on very fine amounts of destruction that will keep you hooked for hours on end.

The most skill based shooter around, hard but fair CS:GO is some of the best $15 you will spend.

A vast community centered game based on the source engine with essentially endless amounts of games if the community decides to make it.
