Alright, final decision.
It will be both RPG and Surivive the Disasters. The RPG will be the temp server until Survive the Disasters fully works. (Which won't be long, but the RPG will take time too add things) The RPG is just something to replace the server with since the server has been passworded for a very long time for many projects. Once the RPG is 100% complete it will be official (which will obviously take forever). This is a dev RPG mod, which means people can play it, but it won't have that much fun features, but it is an RPG.
I think I will set this up:
24/7 Server:
Survive the Disasters (Backup: Basic RPG)
Desktop Server:
Survive the Disasters Development
