Maybe they are doing what the RTR-team are doing.

Depending on what faction you choose, the x-faction will be a diffrent faction(a faction that a alot of influence on your faction).

I really love this idea. And what's making it even better? All the x-factions (or counter-factions) are playable(most of them)! This give you up to around 40 diffrent faction to play as. It's insane!
