D&D Attack Wing

I know X Wing is probably the most famous Attack Wing out there, but I must say that even though Wizkids aren't the most awesome miniature seller out there, the D&D Attack Wing game is really fun and the miniatures stack up good to use in any future tabletop RP games :)

Dogfighting with Dragons has never been cooler. And the addition of ground troops is potentially amazing.

Only thing I haven't really figured out - how many can you actually play with at the same time? The actual box says "for 2+ players", but the rules only covers examples for up to 3 players...
I can't really see the problem of having 5-6 players playing this though.

Has anyone else played it?
