100

from what i have experienced, fan projects need good leadership (clear aims, no endless scope creeping and can avoid drama) plus a core group of major contributors to succeed

also when you inevitably lose someone important to the project (be it obligations or drama), you have replacements ready and dont have the whole project fall over because one person was too important

this team failed at that: leader quits and whole thing disbands

well thats one way to increase nato spending
