what's good ?? I'm Jose B. from another dimension and to me this is me perfect world is this a world with no preoccupations, where everyone is kind to others and a world where everyone can achieve whatever they want to, lastly, I wish for a world where the land has not been that affected.
Honestly I wouldn't change the weather only the gravity but only a little. Also I have to mention that superpowers and magic would exists.
In J.B metropolis land, the rules would change a lot corruption wouldn't be a thing, nuclear weapons wouldn't exists, and all humanity would be united, the governments would actually follow the rules and would do their job to benefit civilians.
Food and clothing would have an explosion of variety making it new types of food and new ways of clothing. like these plate for instance or those clothes, you could dress in any way you would want to.
In my world everything would be automatized every service would robots that could replace a human on some tasks not all of them because humans would still have a chance to work.
Finally, but not least important that nature would a lot stronger in my world with extinct animals still alive.
