I dunno if it's the genre or the medium. I seem to notice that player of Sci-fi games are more inclined to accept new tech in this manner. Wargamers would much rather use minis and model terrain, if given a choice, and die-hard fans of D&D seem to prefer old-fashioned battle maps. These are just broad generalizations, of course.
Has anyone noticed how Star Trek gamers seem less inclined to use map at all? I suppose this makes sense; very few adventures in ST are set on the ships themselves; they usually involve away teams.
We've used D20Pro for star Wars RPG. Found some Star Wars Ship deckplans and some battle maps for Star Wars settings.
It was a BLAST!!!
I also found some maps for our Mutants and Masterminds (2nd Edition) campaigns. A map with some placeable items for superheroes and super-villains to interact with.
