Where is Master of Orion 3? I know, it's possibly the worst part of the series, but it hasn't been included. Maybe it will be released later, as a separate 5,99$ game.
I keep hearing on how MoO3 is one of the most reviled games of the genre - I remember asking on a Mac forum once if it was worth buying from the bargain bin at a computer store I used to frequent, to which all of the veteran MoO fans answered with a resounding no.
Master of Orion 3 was a collection of excellent ideas that were badly, BADLY executed. I once heard it described as a spreadsheet on amphetamines, and that's not an illogical conclusion.
Heh, a joke that still makes me chuckle was when someone on said forum called it "Master of Micromanagement 3".
There was a fun Space Conquest game called Imperium Galactica 2 which I would not mind seeing GOG get.
Reminds me of a similarly titled 4X game that came out the same time as MoO3, Pax Imperia 2: Eminent Domain. It was the first game I ever saw that was able to play itself - I could set my Viceroys all on autopilot and it would just churn away happily, without needing any input from me at all.
