God I played CS:GO and it was the worst fps I've got the chance to buy and play. I might give it a 3/10. But I will hold on to that and see if there are at least good parts to it. The shooting system is horrible and the option menu is too complicated. I played for a few rounds and it wasn't fair at all. I made a headshot by shooting a guy in the foot, like wtf? :D
But, at least I found out that I really, really like CS:S. Might start modding it, swear to god it's better than CS:GO in most ways, except the visuals.
