Ziechael said: Andrew C's Neoseilthir is specifically set up to use 3.5e rules (although could likely be adapted to other rulesets...), it is certainly reasonably priced for the amount of work/content that went into it's creation and is apparently due to turn into a series of modules which increases the scope for a longer term, multi-level, game? There is also The Sword of Morn which is set up for 3.5e play too. There are likely Pathfinder modules (like the Belfum series, Journey to the Red Keep , The Goblin Undertaking and The Breaking of Forstor Nagar ) that could be easily converted for use with 3.5e. Ziechael, I'm actually specifically doing a version for 5E D&D, I don't know any other systems enough. But there are another 4+ volumes planned for the whole Neoseilthir set. And then it might be time to work on a new one, either around the Six Duchies part of Neoseilthir, or farther afield.
