Obviously, at first it will be simple mechanics like most other things. Things like: fences, traps, barricading, etc. (like everyone has already said). However, I don't think it will stay like that forever, and if it does then (IMO) the devs would be really making a mistake. Think about it, say your group has a camp site that is fenced. By this I mean there is some sort of basic fencing surrounding your camp (it could be scavenged metal/wood, pallistades, wooden boards, etc). Let's say this time it's wood. So you have created crude wooden walls around your camp. Is it really that far fetched to go from wooden walls to roofs? Thereby, making buildings and once we have buildings why limit then to just sheds (like mentioned above)? What's stoping us from building cabins, houses, forts, etc.? I'm not saying this would be fast, because it's not. Nor am I even mentioning the problems with destruction (since I would prefer to see it ingame before comenting on that). If you want to be realistic here would it take serious time for a group to build a fort? Of course. Would it be faster to just build a shed or better yet just a wall? Most certainly. But what's stoping us, what invisible hand is preventing us from creating them? Hmmm? For me DayZ is a challenge that never stops and unlike other games it's actually realistic. If i have walls around my camp I'm going to want buildings inside of them. I'm going to want to keep expanding, keep building, keep discovering, and thereby continue to survive. Why limit our future to some super basic model, when it has the potential to be like everything else in DayZ?
