Black Mesa
Considered the “definitive” remake of Half-Life, I’ve been a part of this tremendously ambitious project for over 10 years. It’s the only fan-driven game of this scale to see the light of day, but original Half-Life developers Valve Software granted us a once-in-a-lifetime chance to market the game as a full retail product instead of just a free modification. The game is currently in Early Access on Steam and has sold over 500,000 copies to date.
