A great concept here man.
I like the idea of limited resources, and including consequence of the player.
Puts more emphasis on always being alert to attack, and the defences , guarding comms ,ect.
Looks like a well detailed basecamp and surrounding area ( villiages,towns,complex's)would be the order of the day too.
Very interested with this, and have lots of similarly original ideas on the same wavelength which you might like.
I'd be happy to help out in any way if you like too.
Just how big do you intend on making this ( if its still hot to trot)?
