If you play Eggwars a lot, I am sure you noticed that when the game is already so advanced, you have LOTS of iron in your inventory, but because you don't need it (Excepting for food), you just throw it. But... What if you could buy Gold Tokens with Iron tokens? Maybe 10 iron could be enough to buy 1 gold . This would not apply to diamonds cause players could buy diamond tokens to repair the generator instead of going middle. What do you think?
