Summary
A very worthwhile package.
The Good
The first 20 classics from Infocom, all nicely packaged. Comes with full instructions for each game, as well as the InvisiClues and full maps. The installation process is nice, as it lets you install only the games you want; and all the games can be run from one main menu.
The Bad
The box is pretty heavy (all those manuals, maps, clues, and stuff) and it's very hard to find anymore. I'm glad I'm an impulsive shopper and picked it up the first time I saw it!
The Bottom Line
The games haven't changed, but it's nice to get them all together. The maps and clues are nice, too (but awfully tempting).
