around the time the Amiga died and it didn't feel like anybody would be interested anymore
That reminds me of what made me stop development - it was the birth of the 360 degree game - Ultima Underworld and Doom came along and rained on my parade. The world was going 360 degree mad.
Although EOB came out in 1991, I didn't actually start work until 1992 - mainly because I had no idea how to make the game until I had worked out how to create a 3D world. It took a mere few seconds for me to figure out how to construct a 3D world - it just took a long time for those few seconds to happen.
