While not a "Map Generating Program" I feel this New VTT is a Viable option...Been interested in VTT for several years..tried a View..most fell way short of what I wanted in a program. I feel this one is worth taking a chance on.

Take a look a see what yall think

Skirmish! VT is a next-gen Virtual TableTop which helps to bring your Role Playing Games to life. Powerful, yet simple to use, it comes with an extensive set of features accompanied by a hi-quality content library. Furthermore Skirmish! can be used both on- and off-line to either support your local game table or connect with players all over the globe.

What makes Skirmish! VT truly stand out though is its powerful plug-in system which lets anyone edit, expand or modify it to truly reflect the way they like to play.
