CalamityRanger: If we somehow got the Infocom Interactive Fiction titles I would be so happy. :D I know they wouldn't come with any of the feelies but I'm sure they could work out a way to still get any info needed via PDFs to beat the games.
I'm with you on that one - In the early-90's, Activision released 2 box sets of Infocom games, I think they were called the Lost Treasures of Infocom (1 & 2). Each boxes had a softcover book that included all the instruction booklets plus copies of the feelies that were required to complete various puzzles (brochures, etc). The first box also included the Invisiclues in a softcover book (obviously with the clues already revealed). I don't think the second collection included the invisiclues. I'm sure .pdfs of these books could be made.
Sometime late in the decade (it seems like), Activision released all of the above on a single CD - it may even have included the invisiclues but I'm writing this from memory. I've got all 3 sets (I've temporarily misplaced the invisiclues book but I know I've got it somewhere). I'd love to see GoG release the entire collection that will work on modern computers sometime.
EDIT: I found my CD version ("Masterpieces" dated 1996) and popped it in the drive. It has over 30 games (including Leather Goddesses of Phobos, sadly no scratch and sniff card...) and has the instructions (w/ some "feelies" scanned in), clues, and maps already placed in 3 separate pdfs (900+ pages scanned!!!). The CD also includes install set ups for DOS, Win 3.1, and Win 95.
C'mon GoG! Most of the work has already been done - just need to get the games working in DOSBox.
