I wouldn't pay anything for it. I had it on my mobile. Very fun, but only for a few minutes of time wasting.
Paying $60 for it? It's like you make these posts on purpose.
I have $100 worth of Angry Birds plushies... $60 wouldn't be a big deal. I'm not saying it will be $60. I think $20-40 seems more realistic, but I'm saying if it were $60 I would in fact still purchase it, yes.
