As a former dedicated Insurgency player... Yeah, there were very few people worth keeping at NWI. They made an awesome concept for a game and then had to spend years upon years fixing incomprehensible, Garry's Mod level bugs.
And let me tell you, Insurgency at the end of its life was becoming a humungously popular game, and they announced and released its sequel, Insurgency: Sandstorm far too early.
So NWI had made a lot of very silly mistakes, and yet there is a wonderful game with a wonderful community still there.
