Considering I leave the game running for days on end sometimes for the right map size I wouldn't mind creation taking up to an hour on my rig. When playing Free Orion I always go for a minimum of 1,000 star galaxies and on occasion push 1600 when a new release comes out. The more room there is to expand and the more time between contacts with other empires the better. Even if it does mean I can't get rich trading techs.
All in all I have been happy with the Gal Civ franchise even if it doesn't have the best of gameplay. For that I still consider Master of Orion 3 to be the closest to what I would like even with all of its flaws and festering boils... Now if only Stardock would take the best of GC3 and MoO3 we might end up with the ultimate 4X game.
