So, before I go to sleep, I wanted to ask this question, because I'm in a debate. I've started playing Call of Duty with World at War on Wii, and let me tell you, ironically, it was difficult playing a FPS with the Wii remote. However, over time, I started to just "get good" at the game. I then got an Xbox 360 bundled with Modern Warfare 2. I'm thinking "okay, I understand Call of Duty a little bit", but got wrecked in MW2's beginning. Could've been the adjusting to a new controller scheme. So, after playing World at War, MW2, MW3, Black Ops, Black Ops 2, Ghosts, Titanfall, Battlefield Bad Company 2, Battlefield 3, Battlefield 4, Battlefield 1943, Homefront, and reaching very high ranks at a some what fast pace, you'd think you'd be naturally good at FPSs. So my question again, is Call of Duty an easy to play, but hard to master type of game series? Is it easy because you consider yourself naturally good at FPS? What constitutes mastering Call of Duty? K/D? Pub Stomping? Being MLG? Can anyone pick up the game and just be good at it?
