I just respect any game that has no strings attached. I have mostly given up on iOS gaming because there's just so much niggling and begging and nickel-and-dining.
This will be remembered as a dark age, not a golden era.
Not iOS, of course, but the whole purpose is to feature games that are either free, or have a one-time purchase, whether in a marketplace, or in-app, that provides the entire game, no recurring purchases, etc.
Have there been any attempts? Before you suggest it I should say that I think BeeMinder does not count because of it being upfront about what it's there to do.
The model still being used in the console world.
We might end up going again down that road.
