Amateur gamesThe 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.
Missing gamesThe 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.
TechnologyAll 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.
