I plan to host a Multi-Player game based on this version at some point in the near future. I expect it will require three or four sessions at a minimum. If you're interested, let me know.
I played an earlier version of ToH in multiplayer through NWC a while back and thoroughly enjoyed it. It´s atmospheric, quite challenging, and really makes you feel like you´re playing D&D. It also takes advantage of NWN2´s graphics to immerse you in the dungeon crawl. Highly recommended.
