Make a Supercell account so that no matter whose GameCenter you are on you can log into your base! This would be an insanely fantastic feature because it would mean I could keep my base when I get a new phone. Heres the story: I had an iPad and I downloaded CoC. Every day I would get on and work as hard as I could to get loot to work on my base and over the course of around 6 months I had myself a maxed out Town Hall 8. I couldn't connect to GameCenter however because my family shares an Apple account and my brother's CoC base was saved on it since he started the game a few hours before me. Well we had to sell my iPad and I lost the base. Now I have a new base made on my iPhone 4, but since my phone's so old I need a new one but I don't want to lose my base!
