Did Warcraft 1 and Doom have cross platform multiplayer back then?
I don't know about WC1/Doom1 but WC2/Doom 2 on the Mac also supported IPX to play against PCs in addition to the native AppleTalk support they had. The only time I ever saw IPX on a Mac.
Fun time. Developers essentially have to dig very low into the stack and deal with multiple architectures. The way to build great programmers.
They didn't have to deal with agile/scrum though. Clearly not real programmers ;)
