I'd vote for "Prometheus". Sounds like it'd fit a piece of electronics and is an evil AI in a game. Also, Prometheus was the one that went against the will of the gods and brought fire to the humans. "Lucifer" or "Satan" would have too many negative conotations (yeah, he opened the eyes of man but people hate him for that). Or just for fun imagine a system called Yggdrassil with a controller shaped like a rope around your neck and a screen that looks like an eyepatch (wonder how many know their mythology enough to catch THAT).
