In the scenario I am writing for Project Generations, the PCs play the Reserve Crew of a generation ship who are awakened from cryostasis. Today, I completed the character generation rules for the awakening and character generation process. All of the details for using Project Generations chargen with the Diaspora and Starblazer Adventures rulesets are now set. I still have some specific details to work through for Bulldogs!, but the overall framework is there now and seems to hang together well.
The overall approach is character generation on the fly. That is a feature of a number of FATE games, and has the benefit of bringing people into play rather quickly. Character generation is grounded in the space ark and cryostasis experience through the use of two tables, while also leaving room for some up-front player creativity and intentionality in character design before play begins.
I think the system strikes the right balance between narrativist and sandbox approaches to PC generation. If you don't like to know everything about your character before play begins, I think you will be happy with this. You have room to explore and grow your character, which is exactly what I saw happen in the playtest.
I am happy to have the rules in a more or less final form that feels right to me.
