Activision released two collections of INFOCOM games. These are known as The Lost Treasures of Infocom, sadly, neither volume is currently available. These anthologies consisted of all the games except Leather Goddesses, Shogun, Arthur, and Journey. Here is a breakdown of the games in each collection (these games have also been recently re-released by Activision in themed CD-ROMS called The Infocom Collections, and even more recently in a single CD collection called The Masterpieces of Infocom).

* Volume II originally contained a coupon that can be used to purchase The Leather Goddesses of Phobos at a discounted price. However, more recent sources have informed me that Activision is no longer selling Leather Goddesses.
