In the middle of my search I stumbled upon this:

I didn't knew about it before. I'm not sure what to think about it. Maybe it's fair that they did it; I need to read more. But I'm getting worried.
The moment they'll try to monetize players will be the moment this game will die. People will leave with a bad taste in their mouths. I'll leave with a bad taste. Someone will step up, make a similar game. But it won't be the same anymore. It won't be The Game.
So dear NIA, please don't screw up what you created. Don't sacrifice the game to Moloch for a quick buck.
