The six "bonus" games included weren't by Infocom but rather were the top three games in the Inform and TADS divisions of the 1995 rec.arts.interactive-fiction IF competition, produced by amateurs on the way up.
The only two text-adventure games that do not appear on this CD are The Hitchhiker's Guide to the Galaxy
and James Clavell's Shogun
. Probably they do not appear due to lapse of the license to sell them.
All the games were re-compiled to launch from a single exe. This had the effect of no longer requiring ANSI.SYS in the config file.Information also contributed by
