This needs to happen. I was looking at Forge of Empires (maybe not the best example), and it really puts me down how there's no premium and proper offline city builder on iOS. It also sparked a pretty interesting conversation on /r/iOSGaming, with people having different opinions about the subject. (https://www.reddit.com/r/iosgaming/comments/6q3nda/why_are_there_no_proper_deep_premium_and_offline/) I can understand the money aspect of F2P and the gambling addiction and the always online requirement for such a project, but what I don't understand is how with every other genre there exists a proper premium equivalent; just the city builder is lacking. And yes Rollercoaster Tycoon isn't really what I'm talking about. What are your thoughts on this? Am I missing something or there aren't really any great, premium, deep, offline city builders for iOS?
You can check out Kairosoft titles and see if that would suit your needs. Check out the premium ones.
