No it does take a lot of skill and very good decision making and timings etc. You have to have an open mind in that game I can't even comprehend how much skill it takes it's ridiculous it's fun once you start to notice what you are doing wrong and stuff on how to improve upon your actions and choices. Starcraft 2 is so skill based it's crazy how skill based it is one small little fuck up could cost you the game or one minor attack/aggressive push can win you the game there are so many strategies put into that game to a point where I am like I don't even know.
I can't help but laugh when I try to image you saying this.
But speaking of games that take real skill, Ace combat.
And Left 4 Dead 2 because you see, it's not only about aiming skills there, you also need to know how to effectively use mouse2 to shove off zombies or special infected, there's also things to learn with melee weapons such as breaking smokers tongue before it can grab you, kill a charger while he's charging at you and so on. Not only that, but it also takes strategy, it's important to know what do and where to be at certain moments on both sides and it also takes teamwork (that's what it is all about especially in versus) and understanding how to stick together (I specifically mentioned this since for many people I have played with this seems like a hard thing to do surprisingly).
Tl;dr I'm the best and I play the best games.
