Basically this successor will be the new owner of NR. Will have the ability to create their own staff and manage the game in the way they feel is appropriate. I will remain as an adviser and offer assistance when needed.
As far as paying for the server. Probably the easiest way to go about it is to continue to fund it through the Patreon page. I will cover any deficit up to a point if the Patreon page doesn't fund enough to pay for server costs. Going forward, I will not be taking any money from Patreon and any excess cash over the server costs will go into a pool for use by the new owner in a way he/she feels appropriate.
