Hello Cestvel,
Thanks for the comment, and I agree.
I would like to start on a planet in a system where I know that at least about 10-15 empires know how to get there. I can also publish all system names in a 2-3 system radius, including paths, so that would increase the number of possible participants as well.
We can start small, and maybe it can be expanded to more participants in WotW II a year later.
I would not start the battle untill at least 15 turns have passed from now to allow for logistics. It also allows participants to research that key technology to give the team more power!
Kind regards, AKO
