The demo is a bit outdated. There were some major updates fixing bugs and performance issues a while back. However the game does have a speed control *Upper right corner I believe* That allows one to drastically change the game speed. you can make all your orders while paused and play as a *Turn based* or similar style game also I suppose. Server hosting I would almost say requires another computer to host from. There is a ton it needs to remember and keep track of as there is no finite limit to how large one makes their universe some servers need much better computers than others. From what I could tell when I purchased the game a few months ago, people claimed its original release was lackluster and bug riddled, however things got fixed and added to make it an enjoyable game.
