I would like to suggest to the devs to make available a second island which could be arrived on by clicking a Galleon/Ship situated near the "Gollum " small island on the home island.
From there, set up sectors similar to the home island, where tit ore mines, granite pits and exo trees can be found. Of course bandit camps will have to be defeated to take over this island, and for those at level 50, you will progress towards the new maximum level of 60. Also new troops can be made in the barracks, such as royal recruits,royal bowmen, royal militia, royal soldiers, royal elites and royal cannoneers.
Please feel free to comment, and add further ideas.
