Master of Orion, a turn-based strategy game (with trade items) released in 1993 by Microprose. The game was released for PCs and Macintosh PCs.
The game takes place in the future - exactly in the XXth century. Several races (including humans) have begun to conquer and colonize the galaxy. As in every ecosystem - here comes friction and conflict. You as one of the leaders, you will have to lead your race to victory.
In the game (I mentioned) there are several races available - each has its specialization. You choose the races at the beginning of the game, remember before choosing - it may affect your final triumph. You can finish the game in two ways: by winning the game (elimination of all races) or becoming the title leader of the galaxy.
