I recently found Maptool, which is a GM’s dream. I love describing a place to players, but I have often found that in large groups (which is what I tend to play with) without a visual representation, players can get unfocused and forget whats happening. I have always wanted a way to display maps to players without revealing whats coming.
And Maptool does this.
I will be posting some maps soon for everyone to check out.
