I'm just gonna butt in here and give my two cents. Brandon, you keep saying that sandbox is a "do whatever you want mode". But I, and I think a lot people would, disagree with that view. Sandbox isn't a do whatever you want mode, by that logic the devs would implement a my little pony mod as an option to sandbox mode. Sandbox mode is to change the game to accommodate zombie lore that conflicts with the base lore. However, this still fits in with the devs base idea for the the game. A "limitless" trait that allows all positive traits to be applied has no place in the base game and in no way fits in with the base lore. As a mod, I see absolutely no problem with it, as with a MLP, to each their own. But other than that, it goes completely against the game itself. As for your "no zombies" argument. That feature is more a testing option, for scoping out map locations and bug testing without having to deal with fighting off zombies at the same time. I can't see the no zombies option being implemented into the final game; and if it is then, your argument will be valid. But until then, its just a bug squashing mode.
