Ask HN: What makes the game Doom that special in a Software Engineering context?
E.g. What groundbreaking logic it had implemented?
E.g. Why it is ported to various platforms and always used as a test game to run in the next (fascinating) engine?

- al2o3cr 2y agoWhat groundbreaking logic it had implemented? We consider a lot of what it introduced as "just videogames" nowadays, so it can be hard to spot. Comparing can help - consider Doom (1993) versus Wolfenstein 3D from the previous year: * walls at angles besides 90 degrees * floor and ceiling textures * multiple kinds of ammunition * lighting Why it is ported to various platforms It was open-sourced in 1999, so it's partly about availability. I suspect it's also because it's _possible_ to port to lots of things; it benefits from specialized hardware for graphics acceleration but doesn't require it.
