It doesn't have to be in real time but, they should implement something with base building down the road with farming to some extent. I don't know exactly how farming could/would be able to be implemented but it would be a nice addition to Dayz in its own way. It would have to be tweaked a lot but, I feel it would allow people to come together to work together to survive together. It would make it easier if you had a bigger group. Again, everyone will have there own opinion on how they think this should or shouldn't be implemented.
