I hesitate to reveal the particulars of the campaign in case I decide to run it for other groups, but I am using Maptool and Ventrilo to run a campaign. It is 1st Edition AD&D (with homebrew) and depicts a desperation shipwrecked scenario called Eye of the Storm originally written as a PW for Neverwinter Nights and it is the Aurora toolset I am using for much of the graphics I use in the game. Between MWSnap and Token Tool, this is working well and provides a wealth of material to use. Going into session #16, the players seem interested and one even built a website for the campaign.
So far, despite the obligatory minor glitches, I am absolutely delighted with Maptool. Thank you for providing, via these tools, the opportunity to game again well into my dotage.
We are using maptool 1.3 b32.
