Deadlock Planetary Conquest was a turn based strategy game released in 96 and was one of my favorite strategy games. There are seven alien races (each with its own strengths and weaknesses) struggling for the domination of a randomly generated planet where each of the seven would deploy colonists to the planet. The colony to drive all others off the planet's surface, or to construct a number of cities, would claim the planet for its leaders.
Usualy i dont like 4x or empire building games where you manage colonies and stuff coz they tend to be unnessecerily hard to play but unlike many games of its type this one is rather simple and fun to play and it still runs on win7 :)
Maybe i should make a game page about Deadlock sometime.
