Doom didn't kill the Amiga, Wolfenstein did... Released in '92, it showed where computer graphics were going. And none of Commodore's Amiga offerings came close to it... The then 7 year old Amiga architecture was useless for that type of game and game developers knew it. Software quality declined, sales of Amigas declined... Doom was released, the Amiga had no hope by then... The ball was already rolling... Commodore folds, end of story.
Agree Bloodline. There was a race game using the same technology at the same time, can't remember what it was called. But people were taking notice. Even with AGA, Amiga technology was essentially the same as it was 7 years earlier with the affordable Amiga machine only being a few times faster than the original 1000, GFX speed included. a 386 66 or 486 33 Blew it out of the water when it came to graphics crunching.
Sad but true.
