Wolfenstein 3D was the first game I played to have any association with Apogee (but I didn't know that at the time.) The first game I remember seeing the Apogee logo with was ROTT off the original Duke Nukem 3D game. So Duke3D was probably the first time I really made a 3D Realms memory, and it's been a love affair ever since.
Can't believe that Duke3D will be 20 years old in just two years... Holy sh*t...
