Whatever route you go, just make sure you download the "Adventure Journals" somewhere. These are the kind of games that have you look up paragraphs.
Forgotten Realms Archive is dirt-common because it was released as a budget thing in the early 2000s, when Interplay was doing this series called (I think) GameFest which had two jewel cases in boxes connected by a fold-out. I think that version has the manuals on disc, and actually includes an extra game--an RTS called Blood and Magic (I have the earlier Forgotten Realms Archive, which sadly only has a *demo* of Blood and Magic, but at least it had all the paragraphs and stuff in a single bound volume... as well as the language translation wheels and stuff).
Unfortunately I don't think there's an easy way to get the Krynn or Buck Rogers games, tho Krynn got a full trilogy release on CD-ROM in the early 90s.
