Havnt really had time to read through the whole forum, but are they planning on adding something that adds abit of danger when traveling through the fortresses (except for other players)? Some animal like a bear, maybe a snake or so. Traveling through the forest is (atleast from my experience) mostly risk-free, since you rarely encounter any players there and there is no places for zombies to spawn from. Perhaps add some wood-cabins (with some zombie spawns around/inside them) which would increase the density of players prowling in the fortress in those areas, hunting for supplies.
