DM tools

We specialize in producing aids for role-playing games such as Advanced Dungeons and Dragons?.

Use our tools to generate dungeon crawls or overland maps, villages, towns and cities, underground caverns, mazes stuffed with treasure, building floorplans, whole world maps, treasure hoards, character names, inns and taverns, dice rollers, magical libraries, items and artifacts or a host of graph paper to design your own layouts.

In a recent review of one of our products, ZDNet said "...It can save you a mountain of mapping time that can be more profitably devoted to gameplay...".

Our aim is to remove the grind from gaming.  We hope you feel that our products help to do that.

 I tried the demo of this software, it's not bad...

There are some OSS tools as well that are becoming more and more useful.
