I remember a bunch of game authoring packages from the old days. The Shoot-em-up Construction Kit (SEUCK) made in 1987 by Sensible Software was popular on C64. Codemasters released something called Creations which was demonstrated by one of the Darling brothers on UK Saturday morning tv in the 80s. I remember him making some kind of single screen platform game in it.
One of the most impressive was the 3D Construction Kit from Incentive Software (who also published the Graphic Adventure Creator/GAC). Released in 1991, it used the Freescape 3d engine from Driller (1987) and Castle Master (1990). I remember it being a big deal in the magazines of the time.
(As an aside, I've wanted to investigate the hypothesis that early 90s VR tools like Sense8 Worldtoolkit may have had an influence on modern game engines, but I have never been able to find out much about them)
