Imperium Galactica is a bad game. I think it'd be better to actually maybe complete one of the already existing projects than to add another to the list.
Master of Orion 3 or Imperium Galactica 3.
Difficult decision.
NOT!
The fact that I've got Imperium Galactica 2, and am rather disappointed with it, helps to settle the matter.
Unfortunately, the Kilrathi look-alikes have been removed from Master of Orion, but I figure someone will mod them back in before long.
I enjoyed IGII although it did become repetitive on the lower difficulty levels...you have to say that the standard of the cut scenes where really good as well..
