First of all: Sorry if I am reposting, but i don´t want to read 22 pages of comments, so i refer to the main topic. In my opinion, the basic idea of your suggestions is pretty good, but it would be too much of "oh f*ck, i´m starving, and, oops, i´m also overheating, and wow, i´m still bleeding!" and it would make the players too dependent to strangers, and some of us don´t want to cooperate with anybody they do not know, because we all already learnt something in DayZ: Don´t.Trust.Anyone. Groups of players, which aren´t rare, would still be able to shoot every stranger they see, and I would say that most of us started to play the DayZ mod at least with one friend. It would also cause a lack of fun if you have to care about your damn health all the time, and i don´t think everyone would like to play with this difficulty. All of your ideas at once could make a hardcore version of the mod, but not a standalone version. Otherwise, some of your ideas fit this phase of the mod, like the increasement of the amout of zombies. I think, it would be enough, to increase the amount of zombies, reducing their speed, and increasing their hearing (remember: the hearing of loud sounds, it won´t make any sense if ten groaning zombies hear a crawling survior from two miles away), which would increase the danger of (for example) camping on a roof with a sniper, because they will hear you, and you won´t have enough bullets. This would also increase the use of meele weapons, wire fence, and other ways to defend a camp or something similar. PvP in cities would also get reduced, because you would have to hide or leave the city quick after killing a player (and the zombies would surround you pretty quick). You could also increase the amount of vehicles without worrying, because they will help you to move between citys, but won´t help you to move inside them. A higher amount of zombies would also allow new ways of mass-defeating of zombies, maybe by using fuel to make a big fire, and a hooter to make them going in. Maybe, zombies should be made more dumb, to allow single players to escape from them more easily by getting out of their sight and starting to crawl away. This change would need more accessible buildings, maybe moveable furniture, and ways to get away from zombies without a fight - unfortunatly for the makers.
