I absolutely LOVE this game. Huge fan of MoO 2. MoO 4 is great. I love playing custom races and micro-managing all the planets in my Empire and especially designing and building custom starships.
I've been playing this game since it came out in the 90's. I've loved this game for a long time. (I do wish the sequel, Armada 2, worked on my computers.) My favorite map to play Instant Action on is the Junkyard. I've played that in my head when I didn't have a PC to play on.
