You're asking someone whose never faked their accent why a retard would fake their accent... Gosh, that's a hard one. Let me guess. Could it be to fool people into thinking they're someone they're not?
I've played Day of Defeat for years and years. I don't really like any recent FPS, except maybe Borderlands, but then I've been out of the FPS loop the past while. The most recent has been Planetside 2, but I just can't get into it.
Your asshattery is much more entertaining than asking you information.
Not much attempts at covering it up, I'm same both on and off camera. :)
