If both are f2p they should be comparable yes?
Well - no. Let me give an example. I use Assassins Creed Black Flag to show open world game play while you come up with the retail version of Angry Birds to counter my argument. Both are retail games right? You would find that silly wouldn't you. Both are targeting different audiences and are different genres.
So why oh why do you argue with f2p games only because both are f2p? Because both are free and such comparable?
The business model f2p is NOT the games genre. So stop mixing up games in the discussion.
So please stop using Clash of Clans in a f2p MMO RPG discussion. Why do you refer Farmville 2 in a discussion about World of Tanks. Why do you use Candy Crush Saga as a reference when we talk about f2p FPS.
Only because all are f2p? Think again.
Stuff one game does in f2p does not mean it works for your game. Stop copy/pasting things.
Stop saying "But I see game xyz is doing ... so we need to do ...". You don't know if what they do is successful - you don't have their data.
You assume ... and how one of my bosses always says "Assumption is the mother of all fuck ups"
Watch this making of "Triple Town" for some really excellent advice.
