Economic based 3x with some features never seen in 4x games. Galaxy Union places you in a densely populated galaxy as a CEO of a corporation with a mission to unite the galaxy under your rule. Colonize systems, build colonies, research stations, become rich and commission fleets that will conquer the galaxy. This is a turn based 4x game, includes a global market with fluctuating prices, real life minerals and gases. It departs from the regular notion of only having a handful of opponent players and puts you in a galaxy where dozens and sometime up to a hundred AI players are competing with you. The game is deep enough for a seasoned player and quick enough for a casual player. It features a full 3D galactic map and a 3D system view, also it's a "3x that fits into a 2MB zip file" so you can take it with you wherever you go.
