A Free Version of Campaign Manager is now available for download!
It has largely the same feature set as the Full Version, with just a handful of limitations such as a cap on the number of encounters and fewer textures for map drawing. The Free Version is still perfectly capable of making and running smaller campaigns including using the combat evaluation, player views, and game mode.
Please give it a try, and if there is a feature you're thinking "if it only had X, this would be the perfect tool", then let me know! Your feedback is helping determine my priorities for development.
