This week, word surfaced that veteran developer and publisher 3D Realms would shut its doors, closing a chapter in gaming history that began with a game called Kingdom of Kroz and ended with a cloud of vapor known as Duke Nukem Forever.
In 1987, Ronald Regan underwent prostate surgery, Guns 'N Roses released Appetite For Destruction and a small company called Apogee Software introduced the world to a new way of marketing shareware PC games. The so-called "Apogee Model" involves the free partial release of a full game. If you wanted to play the rest, you had to buy it. It was simple, and it revolutionized the PC gaming market. Soon companies like Epic MegaGames, Parallax Software and id Software followed suit.
