They were quite popular until the 486 came below $2000 then the hardcore gamers went PC. Anyone who was just using it as a games machine went Nintendo or Playstation. There were quite a few Amiga people who upgraded to an A1200 (from an A500). A small amount of A4000/A3000 users and just a few more A2000 users. A great deal of the hardware would have gone to the rubbish tip, back when you couldn't give away an Amiga.
Back then I thought computers would evolve, but in reality they just got more bloated, faster at some tasks inc higher resolution graphics. They got dumbed down too much I guess.
