Hi Jaeger,
I saw your questions here sitting so will answer as best I can for you.
In terms for goals for GWX 4, that is down to Privateer and the Team to decide when that goal(s) has been reached or acheived. As far as I am aware... GWX 4 will strive for the same Historical Accuracy, content, and gameplay experience in SH4 that was strived for and I believe, acheived, in SH3.
SH4 is a superior game to SH3 in many many ways.
as far as I know!
Installation will be via and installer again for maximum ease and convenience for the user base, no doubt GWX 4 will come complete with some optional mods as GWX 1 and 2 did. With things like Light Harbour traffic.
Recruitment is something that Privateer as Project Manager will decide.
We are still on shore leave don't ya know.... well whats left of it! LMAO
