If all the armies in the galaxy fought all at once in a 3000 point game who would win? Why?

I for one think orks would have a great chance because a boy only costs 6 points.

Hmmm...Space Marines?  They are so darn tough!

but there so expencive that the orks would have them outnumbered 9-1

Quality over quantity. 

Axe over armor LOL

nids have no chance. i played my sister and it was 15 on 40 and I won! I didnt even get to use my termies :(
