Hello, it seems to me a very good idea, I would also like you to add a mini game, only for small (new) players, so that they could grow faster and thus attract them, so that they continue playing ikariam.
In this game the score of another player would not be stolen as in piracy, it would only be a race (Marathon), the one that clicks more for a month would receive a bonus in raw materials according to their level of deposits.
I say this from my own experience, and why, I played piracy for more than a year and won first place several times before they appeared, multis and mules, and because I had many raw materials I started buying ambrosia to have Premium account to be able to grow my cities faster and so that the materials won in piracy were not stolen from me.
PS: I write in English because I translate Fránces with Google, I'm from Chile, good game to everyone.
