What is the difference between paid games and free downloaded games ?
Usually with Free to play (F2P) games, they gain hackers quicker and are dominated by the in game purchases. Like buying special coins foe 10 bucks which allows you to get some shotgun that can shoot people from across the map. But every now and then we get a good F2P FPS. Right now, its Dirty Bomb. http://store.steampowered.com/app/333930/
