I think all tents and bases should be at least encounterable, and once "found" you can return. Tents in mountains and trees would be more difficult to find then those on deserts or plains. Bases should have a bonus to find (they are larger installations) in encounters. Will this make it more difficult for factions to maintain large amounts of "floor" carpeting, perhaps, but thats the whole point. Fight to defend your turf. Only the strongest and most active factions could maintain secure bases, while other smaller ones would routinely get raided however because they would have less wealth, probably wouldn't attract as many mauraders. This would make you carry around your "prized" possesions rather than thinking you have the luxury of "safety" in the wasteland.
Building vaults is stupid yes, but building cars? Why not? SOMEONE makes them in 2238, why can't it be one of us?
Yee, it is so easy to build car on nuclear engine in post apoc world...
You can build plasma rifles and avenger miniguns in 2238....need I explain?
Yes,because we have detailed blueprints explaining how to build them.You can't compare a minigun to a car.
Did someone say blueprints for bases?
