Sure. Elder Scrolls Games (MODS!), Get some emulators. Just google emulators and you will find many sites. The Binding of Isaac Rebirth (One of the most popular rogue likes out there. Also other great Rogues are Nuclear Throne, Crypt of the Necrodancer, Rogue Legacy, and Spelunky. For Multiplayer I would get Counter Strike Global Offensive. Also check out Insurgency and Robot Roller Derby Disco Dodgeball. Some other awesome games for PC are the STALKER Series. Metro Series, Terraria, Kerbal Space Program, Space Engine (Free). I got a lot more I could tell you to get, but I would be here all day. And make sure to sign up at Humble Bundle and Green Man Gaming as well. Also get an Origin account. (they give out free games time to time)
