New Game Plus starts you in the same place, same face and family - but you now have dwarfism. Every aspect of life will be that much more challenging. Everything from dating, transportation, even securing an accessible living space.
Note though that this form of new game + is quite difficult. The enemies are more numerous, you have fewer starting resources, and the rules of the game are stacked against you.
Every post you have ever made on the internet and ever bit of data that has been collected about you is being collected into The Database, which will then be fed into an AI that will simulate your consciousness.
