It's astonishing to think that the Amiga hardware was done in 1984 and the A1000 came out in 1985 - the same year the NES released in the US! It took Nintendo until 1991 to come up with something roughly comparable power-wise.
From what I understand in the US the Amiga slowly petered out without never truly taking off. In Europe the A1000 never was a thing, but we had four years of the press talking about this mythical monster of a machine and its custom chipset. Then in 1989/90 all of a sudden everyone bought A500s to play Kick Off and Speedball II. That 89/92 period was glorious.
At least in southern Europe Wolfenstein wasn't regarded as a killer app at all, it barely made an impact. Doom and Wing Commander most definitely were, though.
