(1) Is "technically" possible to host a dedicated server that would allow users to play in the same world via the single player story mode and a mod add-in?
(2) If is is "technically" possible to host a dedicated server, do you think we can get GTAV users to contribute to a fund to pay for it?
(3) Would it be possible to add a poll to this website to (a) see how many people would be interested in the dedicated server and (b) also if they are willing to help support it via financial contributions?
It would be interesting to see. There may also be a tech wizard out there that would be interested in setting it up.
