It's been only a week since The Elder Scrolls Chronicles larp had been announced. In the meanwhile it's been worked on, a lot. In that week Marko wrote the rules, inspired by the game mechanics and lore used in the computer game series, ConQuest ruleset and Chronicles of Demgard ruleset.
A couple of us helped out with the rules - with the suggestions, balancing etc. - and the rules were considered ready for some initial playtesting for some combat balance. A couple of combinations were tried today at my place, and they worked out reasonably well. Mechanics which were present in the system really made it feel like Elder Scrolls to me due to how they worked.
A newer version of the rules was produced afterwards, with few kinks ironed out. It's deemed good enough to go public - and open itself to outside comments, and perhaps a public playtest?
Rules (currently in the version 1.0.4) are split into three parts. The first one is Core rules, which are basic rules that are in theory the only thing required to play and participate in combat (if you're OK with being cast into a needed, pre-prepared role that's needed on a larp) - it contains 12 pages of general mechanics and effects.
Expanding that, there are Character creation rules and Gameplay rules, which are of a concern if you wish to create and customize your own character. Follow the development blog here, or join the newly opened Facebook discussion group for more info on the Elder Scrolls Chronicles larp.
