I had originally wanted to gradually reveal an organic system of determining what the character does, but I should probably front-load some more system info. As decisions and choices become available to the character, I fully expect (and hope for) everyone to have different ideas about what they want the character to do. If more than one person wants a certain course of action, that choice will get more weight in determining what happens. There are other things that will give comments more or less weight, but I'll leave them to be discovered. After they're weighted, I'll roll some dice and see which personality was strongest and won out! Then, in the next Tekumel game post, the character will then take the actions of the dominating personality.
I'm hopeful that this 'Play-by-Blog' idea will work out in an interesting and entertaining way, and people can use it as a vehicle to both learn about Tekumel and share their knowledge and experiences of Tekumel, and at the same time develop some cool characters-within-the-character. And have fun!
