Doom is probably the most obvious example of how the PC eventually came to overtake the Amiga’s graphical capabilities, but I think it’s less well known that it took even longer for anything to overtake the Amiga’s audio capabilities.
Demoscene creators were putting out fantastically creative polyphonic rich music on Amigas for years while Doom-playing PCs were still blip-blopping.
Even when Sound Blaster type cards (with sampled instruments) became popular, MIDI was the standard of PC audio, which couldn’t hold a candle to MODs.
The MOD music format actually outlived the Amiga, being used in 1998 in Unreal and in 2000 in Deus Ex.
