DOOM (23 Different Platforms)
You’ll note that old PC games tend to have a lot of different ports. This is partially because, at the time, there were many different computer platforms to choose from. Then, as consoles came out, we saw them get ported to them as well, and now, in the current day, they are ported to mobile platforms for retro gaming purposes. DOOM was released on such platforms such as the NEXTSTEP, the Atari Jaguar, the 3DO, and the Tapwave Zodiac, according to its wiki page, but that’s only the beginning. DOOM has been hacked onto printers, TVs and practically anything with an LCD screen. Heck, at one point, someone ported DOOM onto an arcade machine found inside DOOM! Now that’s meta.
