Well, for one, it's not like I can prove myself to you guys, so anything I do can easily be refuted, and thus I can be called out on it, even though it's the real deal. This IS 4chan. Besides, if I reveal my identity, I could LOSE MY FUCKING JOB.

The higher-ups hate Epic because it doesn't sell as well as the main game. Yes, they're the money-grubbing bastards you've been led to believe they are, but on the flipside, the company's had to do a few minor layoffs for some of it's lesser-known writers and employees lately.

If the company goes belly-up in the next fiscal year, or otherwise needs to have some intellectual property sold, I won't be surprised.
