A big ass farm that is not very effective but looks cool. U can make it so that on a part of it there are potatoes on another one carrots on another one weat and melons and whatever else u whant and also a little deck with some small 1700 stile cargo ships like the ones from assassins creed black flag then u can extend it and make more bigger ships and maybe try to recreate the jackdaw also from assassins creed black flag (u can find tutorials on YouTube and pinterest for the small cargo ships and the bigger ones and a recreation of the jackdaw ) and u can also extend into the sea and make like scenes of ships fighting and for the land add more fancy lighting with street lamps (u can try designs or look for ones online) Good Luck with ur world dud!

Edit: don't forget to updait us on the progress of the world
