We reported regularly on the rise and rise of social games company Zynga, but now it’s time to report on its tough times. The FarmVille publisher announced preliminary financial results yesterday, telling Wall Street that it expects to post a net loss of between $90m and $105m for the third quarter of this year. Zynga also lowered its outlook for 2012 as a whole, admitted to “weakness” in the revenues for several of its Facebook games, and copped to a writedown of $85m-$95m on its acquisition of OMGPOP, the developer of Draw Something. That’s nearly half the value of the $200m acquisition. The news wiped 20% off Zynga’s share price, leaving it at $2.22 – compared to $10 at the time of the company’s IPO in December 2011.
