Can you elaborate on why you think of Apogee? When I think of Apogee I think "Gee, I wish my Apogee product worked on Windows"
* "more or less" because the business structure is more complicated than that and there was still an Apogee Software alongside 3D Realms, but for all practical purposes, what was Apogee Games became 3D Realms and then died due to the Duke Nukem Forever project.
