Great thread G,
Gotta say I play my best when I am relaxed, easier said than done. For example - when I was playing MW2 I can remember panic knifing into thin air when I was meaning to fire my weapon at someone 20 yards away. To this day, I still have to tell my hands to relax.
I'm not that great when it comes cod controller and reflex skill. I blame Zelda born reflexes and not the best pair of eyes,,,, hey... I got to blame something, right. However, I do notice that when I totally forget about being self conscious over KD or just generally sucking - this is when I play really well. With experience I've learned not to give a rat's bum about others expectations of what makes a good cod player. Any stats I look at now I just benchmark against myself,
To nuttin, being tired is horrible for cod. I was even playing Squad mode against bots a couple of nights ago, I was getting owned because I just couldn't pay attention.
