In all the years I've been playing since Closed beta, I don't have that many hours:it's a viculious cycle you can only break if you realize the gameplay remains the same regardless if you played 10 hours or 1200 ( many with that playtime)
Though, between you and me, the real end game of Warframe is scamming your fellow men on trade chat, that shit is hilarious. I used to make so many monies off of that. See, the real trick is to get people to help you manipulate the prices of certain items in trade chat so people can't ascertain their real value. Obviously those who are smart can tell the price discrepancy and will call you out. Still, it's soo fun!
