Dude, I KNOW Dre knows who Epik is. First of all, Epik has worked with DJ Focus, who is a producer with AFtermath records. In addition to that, Game is signed to Dre. I'm sure Game had to get Dre's approval to appear on Epik's shit.
I don't know why, but Rukas, you seem to have something against Epik and I don't know why. I personally like the guy and hope he can bring something new to the table.
Also, another thing, Game even mentions Epik on "The Documentary".
I've actually interviewed Epik before, in August of 2004. I put the interview on my website. Epik is the real deal. He may not be an Eminem or a Nas or Jay Z...but dude is only 18 and has PLENTY OF TIME to better himself.
