Psychotica

I just got this game yesterday and I was wondering is there a way to continue playing without the game ending in a specific year? I am kind of looking for a game where the absolute goal is global conquest and I don't want the game to end at a certain year if that hasn't been accomplished. Lastly, is there a way to have the computer play itself? I work from home and I kind of wanted to have the computer playing in the background while I am working. Thanks..
