Out of these, trenches is the worst in my opinion. It's ganeplay is not very deep, you just have 4 types of Units and 2 types of Artillery... It lags and buggs and crashes easily in some modes (zombie mode is unplayable after score 3000...) As I said before, atm Warfare Inc may have more features, but in the end it's just about massing combat units to overwhelm the enemy. It fails at the Strategy part, which in very importand for Real Time STRATEGY games. If you wait a bit more, I'll finish my review which points out all nice things about Red Conquest... But I would recommend getting Red Conquest instantly ;-)
