I'd suggest considering adding a 'Classic D&D Adventure' catagory for recreations of actual D&D modules from 'back-in-the-day'. I've seen The Keep on the Borderlands (which was fun) and Ravenloft (haven't played) but I definately try to keep an eye open for this kind of stuff.
Played through both of these over the weekend and found them to be the best foundry content I've played to date. They were emersive and actually did a very good job of capturing the essence of paper & dice D&D from the proverbial 'Back in my day'. I've flagged them for half a dozen of my mates who've started playing…
