Color makes a difference in team games?

There is an online game of capture-the-flag where players are assigned randomly to a team of four: red or blue.
After 493495 decisive games, red has won 250545 and blue has won 242950.
The probability of the red teams doing this well or better by pure chance is 1.5383258×10^-27 -- so basically, impossible.
This seems to prove that the players of this game play better when on the red team than on the blue team. Possibly because red is considered the more aggressive color?

I just checked and the totals, not counting ties, are:
Red 250629
Blue 244693
Total 495322
I show that red is 8.43 standard deviations ahead of expectations. The probability of luck that good, or better, in a fair game is 1 in 60,035,983,156,335,600.
I don't know a thing about this game. Are you sure red doesn't have some advantage, like going first/last?

Thanks, Wizard.
What did I do wrong in my math that we got such different numbers? I used this link to come up with my probability -- http://www.wolframalpha.com/input/?i=chances+of+250545+heads+in+493495+flips -- since the chances of winning a fair game not counting ties is 0.5
About the game:
It's a very competitive capture-the-flag game. There is no turn-based advantage as the game is played in real time. I cannot account at all for the red team's advantage other than the cultural psychology of red as an aggressive, winning color.
Personally, I like blue better, so I am disappointed with these numbers.
Here's a video of the gameplay:
