Oh, you came here for facts' civ#4? Bad news, this isn't that. Good news, I have a better suggestion.
We have 14 civs. Which is a good number (can be better with my 3 new civs).
But you know what we actually need more of?
0 A.D
My suggestion - *hold your breath* 0AD 2.
We need 2 0ADs.
I might have actually outdone myself (No, I don't want an Oscar, Grammy or Nobel Prize, my contributions are solely for the betterment of society)
This new 0AD will have no new features (Development community needs rest). It is meant to split the player base and cause madness and confusion.
Buahahahahahaha I am mad scientist! Chaos! Conquer!
cheers,
facts (oh facts)
P.S: Maybe look into 3 0ADs?
