Doom which was countless fun for people up to this day who make mods? (E.g. the great Myhouse.wad that was perhaps FPS of the year... 2023)
Quake, which was a good game, but arguably a better engine that lead to things like Half-Life 1?
Other games?
Shared the code to Doom and Quake?
I guess you dont understand how big of a game Doom was. The first episode holds suprisngly well up to this day, even after hundreds of doom-clones as they used to call FPS games.
The engine enables people with actual creativity to realize their vision. I believe Carmack was part of that creative process, but the condescending tone of your comment really isn't appropriate because in most games the engine is just a means to an end (nobody sane idolizes games because they're using unreal underneath, for example)..
