Exactly. I'm so annoyed with people nowadays that just expect every update/new version to be free. They think that when you buy one app, thats like a lifetime license to guarantee future content, updates, add-ons, etc.
Just go look through reviews in the App store and you'll see what I mean. Like half the reviews are people bitching saying things like "oh you haven't added new content blah blah I want my money back I already beat the game and now I have nothing to do."
Peoples' sense of entitlement truly annoys me.
