The aether is meant to be a Free-build world, so if you enjoy building or looking at buildings I would recommend it( You can also view the aether on the livemap). Though without fly it is a bit harder to navigate the flying islands.
No i dont think so because you cant have any farms larger than 15x15. The only way i can think of making money is by charging money for tours.
Yeah like lets say you make a maze or an art exhibit. You could charge a fee for allowing people to view your art work.
