Trench Conquest
Over there! Send the word, send the word over there- that the Yanks are coming...
Trench Conquest is a batch strategy game based in WW1. It has two different game modes that are turn based. One is graphical where you try to take over the enemy trenches and the other is where you have to conquer the enemy in WW1 with large-scale attacks. The second game mode is a more advanced version "WAR!!! 1900s Conflict" and has a simple morale system, basically don't just keep sending your men on suicidal charges, and a bit of randomness that determines whether or not attacks fail.
