So many more options....
What about free, with extra DLC?
Free, with ads?
Free, with a "premium" membership?
Monthly fee? (MMO folks)
Heck, what about freemium? If you really want to make money, it's definitely a great way to go.Flurry says so.
My company KNOWS so (we help devs do it).
So much more to "free" than meets the eye.
