Although the company is known these days as the creator of the Steam platform, as well as hosting eSports tournaments, there was a time when Valve was one of the most prolific game studios going. From the influential Half-Life series, to both Portal 1 and 2, as well as such popular deathmatch games like Team Fortress 2, it was a developer that always seemed to be on the cutting edge of gameplay and storytelling. At one point, Gabe Newell and company began working on a space pirate themed game, which was sadly cancelled. However, some concept art has recently emerged showing what it may have looked like.
