Now that we have the wiki mostly established, and people have written FanFiction here, I decided to give you guys more freedom to create.
There are designate threads there for creating your own units, factions, weapons and even tech. Go crazy and have fun there. There's also a section for FanFiction, of course.
I have a separate thread set out for you guys to suggest what other creation-specific threads should be made.
Go have fun, comrades. :D
