angry tapir writes "This week marks the 20th anniversary of the release of the first Commander Keen game. For those too young to remember, Commander Keen was a series of shareware 2D platform games for the PC released by Apogee Software (aka 3D Realms) developed by no less than id Software — the developers of Wolfenstein 3D, Doom and Quake."
