Just FYI, the maximum length for network cable is 300 feet (:
A friend of mine, lives down the street, owns a gaming center where he has four 45" TVs with XBoxes networked. They play a lot of Halo and occationally I'll go up there. It's good fun when you have a lot of guys that are fairly good and doing some kind of team game. I wish they would have had it be four teams, though, and maps designed for it. Imagine Blood Gulch in a + (four wings with bases) formation instead of just a long line with bases at each end. Then four teams of four men (red, blue, green, orange) playing capture the flag. Cool stuff.
They could have also had color options for teams. That would have made a lot of sense ... If all the colors for the individual players were available for an entire team it would have been cool. Or let each player keep their own color, but wear a team designating 'jersey' or something ... I mean, there are giant green arrows as it is. What more do they need.
