Not just a ladder
I've had the following idea for quite a while. Instead of having just a ladder, make a league which is purely Aliens vs. Marines. Create a universe populated with planets, and make the goal of the leauge be to take over every planet.
In other words, instead of just having a ranking system, create a sort of meta-game on top of NS, which ties into the backstory. Basically an excuse to have matches, and at the same time stay within the concept of NS (not playing games just for bragging rights but have the league be a sort of game as well).
The rules would have to be formulated (i.e. how many teams can participate per session, how one attacks planets, etc etc) but I'm just curious if anyone thinks this would be a fun league to play in?
