I originally bought this on Steam during a sale. It's a great game and performs well. I had little to no performance issues at the time of release. The game plays more like a classic Doom game. Weapons feel good and sound good. Everything in the game feels nice and beefy. I wish multiplayer worked on the GoG version, despite this game being 9 years old. I'm hoping GoG will find a way to get multiplayer to work.
