Hi all. Just did a bit of catching up on Sierra and incidentally came across the following text, which confirms the existence of a KQ2 demo I had heard about some time ago:
If you've never played an adventure game, and are reluctant to part with $49.95 to try King's Quest II, check around for a free demonstration disk. Instead of spending a lot of money running advertisements, Sierra On-Line has produced 15,000 incomplete versions of KQII and shipped them to dealers and computer clubs across the country. If you like the demo, you'll love the game.
This snippet is from an edition of Compute! from 1985, which would mean the demo in question probably uses AGI v1. I recall that it was said to have a time limit, so it would be interesting to see how they implemented that. Anyone ever saw this one? There are (or rather, were) apparently 15,000 out there!
