I've been running a conversion of good old D1-2-3; the PCs should reach the Vault of the Drow tonight.
This is the first time I've ever run the D series, though I have wanted to do this for 22+ years. We're having plenty of fun, but I am beginning to wonder if this adventure is actually an example of one that reads great but plays bad.
There are all sorts of wonderful descriptive passages in the original text -- the eerie underworld setting, the alien shrine of the kuo-toa, the bustling and decadent city of Erelhei Cinlu. And I am totally down with the concept that these modules are not so much focused adventures but the skeleton of an open-ended campaign setting. To that end, I have prepped myself for plenty of improvisation in order to allow the PCs the ability to "go off the map," should they wish. I have adventure hooks galore at the ready.
The problem is, the basic premise of the setting is an extremely hostile environment teeming with a very evil, resourceful, and powerful (if factious and chaotic) enemy. An enemy that is probably aware that the PCs are on the way. An enemy that has had their bad-assedness built up for months and months.
Given this backstory, there's very little to encourage a reasonable player to take their time and "see the sights" of either D1 or D2. My players have a very healthy respect for the dark elves and are determined to march straight and swiftly for Erelhei-Cinlu, sack the Eilserv estate, and get the heck out. They didn't want to mess with troglodyte warrens or kuo-toan shrines. They were more than happy to quickly push through both areas, keeping a low profile all the way. In their mind, the less action, the better.
So, after 6 months of running G 1-2-3, they blew through D1 and D2 in about 3 sessions. Considering the amount of work required to convert those modules, I am rightfully wondering if the effort was justified. Hopefully I can stretch D3 out for 3 or 4 more sessions to get some value out of them.
From what I can gather through reading old-timer forums like Dragonsfoot, or even EGG himself recalling his experience, it sounds like it's pretty common for players of the D series to just hustle through the whole thing (and miss most of the "good" parts).
