RadFallout100

I was wondering if it would be at all possible to re-release the game some time after initial release as a single player and co-op sandbox. I don't know much about servers, or online gaming, I'm usually a single player/RPG/open world kind of guy, and I don't really get into multiplayer that much. I figured that if it were possible, that it would be a great opportunity to fill the gaps of disappointment left in the wake of No Man's Sky. Even if the answer is a definite no, I would at least like to know why it isn't possible. Thanks for any help, tips and advice!

I was wondering if it would be at all possible to make an alternate release (maybe some time after initial release) that is sort of like the structure of Minecraft, with single player survival and/or LAN co-op. I don't know much about online games, but I AM assuming that they take up a lot of space, which would be an issue, and it would probably require maximum hardware, but if it didn't hurt sales (assuming it's possible) then I would think it would at least be a good idea experimentally. If the answer is no, I am at the least anticipating some information regarding how exactly the game functions as an idea of why it wouldn't work. Thanks for any information!
