From the release:
Chronicles is an open source Skirmish Tabletop Role Playing Game.
The rules are absolutely free and we encourage people to let us know what they think. So download the core files, try out the game and let us know how you feel!
Some of you may remember we released a previous version on January 21st 2011. This version is very different, so if you didn't like it back then, perhaps you will now!
