Honestly, I’ve never even heard of Zynga.
It started, became great, declined, and now is about to fail, without my ever having heard of it.
Not sure if that says more about Zynga or about me.
Zynga makes games for the iPhone and iPad. They’re a hugely successful software developer and arguably one of the most premiere developers on the platforms.
They’re somewhat disliked, however, because all of their games are complete ripoffs of established or competing games. Their Modern Combat game series is a ripoff of Call of Duty: Modern Warfare, which is possibly the most popular video game series (in terms of sales revenue) currently running.
