I'm guessing you don't believe in games at all...? I think this would be more of a discussion about whether games are a good thing at all, but that would probably be mostly opinions.
I think that was the point of his comment. It's not about the payday, or the rewards. If you totally and completely enjoy what you do, then work conditions like these aren't poor. In fact, pretty much every game company, and many tech companies have the same work conditions. I don't understand why Zynga is the only one to get blamed for work conditions.
And how could I convince you otherwise? By pointing you to my portfolio site or a linked in account?
Maybe this post is badly timed with all the other negative stories going around, but I thought I'd just address one thing which I believe for sure isn't fairly judged about Zynga.
