When it comes to gaming, every real gamer should not be new to the fact that there are games that are not free. This is also same for PC games as I have seen some games that I like on PC, but can't play because of the high cost. What free PC games are you playing?
I used to play a lot of Team Fortress 2 back in the time for hours and hours a day. I think I got a little good at the game but then for some reason I stopped playing it. Another free game which I like is War Thunder. It's a war game where you can play as a tank, plane, submarine, warship and have some fun destroying other people.
