Utopia the Creation of a Nation is a strategy game. It was published by Gremlin Graphics, and developed by Celestial Software. It was released in 1991. The game was released for MS DOS, Atari ST, Amiga, and later the Nintendo NES.
It's like SimCity, but with an added military element. Your job is to be Colony Administrator for a new colony on a planet in the far-off future. How your colony grows is entirely up to you. It's your job to provide your new colony with power, life support, employment, housing, police and entertainment, and to obtain a high Quality of Life rating from the colonists. There are hostile aliens on the planet, so you must be both mayor and general, focusing on weapons research, intelligence, and the building of weapons.
This game keeps you on your toes. So many things could go wrong at any given time, and you have to focus on a lot of different variables at once to keep your colonists both happy and safe. The graphics are beautiful considering the game's age. The gameplay is incredibly polished. It'll keep you coming back again and again.
