You don't seem to understand. I mean a server that's open 24/7, joinable and leavable at any given time. No goals, timers or pressing matters are presented. You just join, and do anything you please with your city. Basicly just surviving, building and managing your city amongst other people who do the same, with no "war" or anything set to reach other than what you want to reach. This would be great for new people to discover everything the game can do, and for more experienced people to develop better strategies and skills for war games and such on servers where there are set goals.
You can join, build and manage anything you'd like when on this "free" server. Build a massive metropolis? No problem. Trying to find the best way to get enough resources the fastest? No problem. Finding the best set-up for defence? No problem! All within a server which allows you to do anything you'd like.
I think that would be aweful. Imagine when a guy is already in there with a giant massive army. And when you join you get immediatly overrunned by them. It seems like a very VERY bad idea. I'll stick with the fair gameplay way, where everyone starts low. I don't want people giving themselves an unfair gameplay.
