First-mover advantage

I think the advantage is last move.. because you get to tally the opponent's moves and as well observe more happening before your very first move, and then each after!

From https://www.chess.com/clubs/forum/view/4-player-chess-statistics :
"ffa wins (excl aborts)
23687 red
23786 blue
23400 yellow
24218 green"
Congratulations ThePEPSIChallange! There's sth like a last-mover advantage.

Any advantage there might be for any of the four positions could be mitigated by the fact that at any time any player could attack you and give advantages to the other two players to gain position against you (especially the player to your left). In 1v1 there are no 3rd or 4th parties to disrupt White's momentum against Black (assuming best moves). It doesn't really matter how good Green's move is against Yellow if Red then checks Green.

mccp1987 , you are of course right.
Neverthless, I don't believe that the initial position is perfectly symmetrical. It seems almost sure that one color has an advantage, maybe very small.
ThePEPSIChallenge hypothesized that it is green and the hypothesis finds support in the statistical data.
As there is a first-mover (White) advantage in 2-player chess, we should also (or even more so) expect the phenomenon in 4-player chess.
Do you have any statistics how often Red wins in FFA games?
