I don't exactly remember where rocket said that, I watched and read too many interviews the last few days, but he mentioned, that the Inventory system is currently in a development stage, where the functions are implemented, but the exact design of the UI isn't finished yet. He also said at various occasions, that they are going to implement some functions they believe to be extremely innovative and they don't want any speculations or people copying it, before it is released. Considering what he went through with WarZ, it is very understandable, that he is careful with what he says, promises and shows. And in a way, not knowing it in advance will increase the awesomeness we experience when we finally see it. ;-) Rocket said that's also important to him. They will start with those three, but more will follow. Also they want to allow customizable skins, so the community can import their own. He even wants players to be able to use their real faces if they want to. According to the interview yesterday, the development of the characters will be the main objective in the next month, before they tackle base building and vehicles. With always-spawned zombies comes the problem of entertaining them while noone is there. I could Imagine that some walkers just roam around the country, following distant lights or sounds they heard, while other zombies might just lie down and wait for something to move. I just hope, that they will respawn in locations, far away from players. Only few things as annoying as having a zombie coming out of nowhere right next to you... I would could imagine, that hordes of zombies coming into a town from all sides, because they heard shots would give a greater experience than always having to sneak into towns that are already fully infested with zombies. Those hordes could be, at random, filled up with a few more respawned zombies, increasing the overall zombie danger every time someone blindly shoots around a village, while it would favor those who keep a low profile and kill silently. The only fear I have is, that the gameplay wont be as balanced, so that groups as individuals and bandits as heros have equal chances to compete. But as I, like rocket, prefer the PvEnv component and the collecting over PvP aspects, I doubt that any inbalance in the standalone will be to my disadvantage.
