Dating myself...
Hi all,
Well, I may be dating myself but here are some of my favorites, in no particular order --
1, Enchanted Wood by SPI for Dragonslayer; all sorts of fun things within these magical woods and just made for an interesting curiosity to expand upon... (in their own way, Blade of Allectus and Palace of Ontocle were neat as well)
2, Staff of Fanon series by Columbia Games for Harnmaster; interesting trilogy complete with a dungeon crawl in Kiraz (2nd module) and extra-planar trips (3rd module).
3, Village of Hommlet by TSR for D&D; just a nice place to start adv after adv...
More as I think of them,
