SO you want to play for free and want more work done on the game....
The game runs on servers, these need to be paid for, that's hundreds of $$ each month to keep a few servers in a few data centers around the world (that's cloud stuff) up and running. Now you need someone to fix the bugs.... but he has the audacity to want to be remunerated for a small portion of his time!
I know you work for free because you are a great person. I'm sure you are in Africa now building a school out of your own pocket because it's the right thing to do, but most people (me included) are selfish and want some form of payment for the work we do, hence someone has to pay the company I work for, I can get paid, so I can pay my tiny $1.99 per month dogfight subscription
This economics less is free, but read it fast because net month I'll be moving to pay per view to cover the cost of my time to write on the forum
