I only know of two WWs recruiting right now. Meta WW, by.... Ramsus and Bladescape. The other is Writer's Block, by me.
Meta WW is.... far from simple, it is going to be a combination of variants. ALL TEH VARIANTS!!!!!
Writer's Block is still not simple at all, but at least there are no secret roles or events. it's not hard to say it will be simpler than Meta WW (sorry), but it's still not "relatively simple". There's six factions. SIX. And everyone has TWO powers. Yeah. Far from simple. But, again, sorry to the authors of Meta WW, it will be simpler than the other currently recruiting.
If there are others recruiting now, sorry, I missed them in my glance through, shoot me a link and I'll probably join that one too.
