Answer 1

Because Doom’s code was made open-source. In the gaming world, this is historically rare, few games legally release their source-code to the public. Because of this it means that anybody can both legally and easily port the game to w/e they want. Doom also came out at a time where computers were so primitive, that even the cheapest electronic devices today are more powerful than the average desktop PC form the early 90s was. Put those two things together and bam, Doom runs on smart fridges.
