The Top Ten Most Challenging Xbox 360 Achievements of All Time (So Far)

Roku -- 06: Forza Motorsport 4 "Factory Driver" (60 G)

Required Action: Get any Car Manufacturer to Affinity Level 50.

On the face of it this may appear to be one of those Achievements that simply comes with time -- but considering that you cannot use the same car manufacturer for every race (not even close) -- it clearly requires specific efforts to unlock. In fact the developer for Forza 4 -- Turn 10 -- declared outright that "our target was to have less than one percent of our players have any manufacturer up to level 50 within 24 months." Oof!

We are sure that they were not counting on the hardcore car racing gamers who eat, breath, sleep, and... you know... their favorite driving games -- so it should not be much of a shock that just six months after the October 2011 release an average of 5% of gamers who play the game have it unlocked it.
