When the original Crowther and Woods adventure ended up on Compuserve back in the early 1980s, the players would go through the same puzzles, traps and effort that many before them (and countless after them) had to. But when they were done, they were done; the replay value wasn’t all that great. So Compuserve, being a money-making entity, did what a number of people did: they extended the dungeon.
The original adventure was 350 points, which you gained by performing different actions or acquiring treasures. The New Expanded adventure added more puzzles, and more points, inviting people back in again (for additional hourly fees).
Now, granted that this is not what you would exactly call “Like New” condition, but you can see the difference from the previous map that I referenced, and especially how they had to struggle, again, to get all the crazy pieces in.
Something about these artistic portrayals of (mostly) made up spaces seems to set something off in me internally, in a good way. I like the idea of an artist having to both know the game, and the descriptions, and somehow reconcile it all into a functional space.
