Only fools think this mod would be fun for more than a few days without PvP. PvP brings adrenaline rushing scenarios and variety into the game. If it was just PvE, you would just round up zombies, run into a building, loot and repeat. There would basically be no fear of death unless you pull a lot of zombies in the middle of a field. You have no need to play 'Splinter Cell'. With PvP you need to be cautious how you bring attention to yourself. Do you throw flares in this area or is it too dangerous, should you use chemlights instead or would that still bring too much attention? You need to make sure you are watching all areas at all times, in fear of a sniper. You need to watch your back, or hope that a 'friend' will watch yours for you. You have to be cautious to unknown sounds - do you show yourself? How many are there? Are they friendly? It is a zombie? Do you stand still and wait it out? After time, players start making squads and gangs, creating an extremely dynamic playthrough everyday. I haven't had this many adrenaline rushes playing video games in a long time. In this game if you die, you probably lose a lot. Dying is a big deal - all of your items are lost, your bearings are lost, none of your friends (if you banded together) are near you. You have to start from the bottom again, and that takes time. I think PvP is vital to this mod and makes it amazing.
