Definitely don't agree there. Fortunately we live in a free country and I am quite happy allowing you to express your ideas and opinions to spite those bastards who attack us out of frustration that their medievil system of Religious government doesn't work!

Sorry. Thought I was Dennis Miller there for a moment.

I used to agree with you. What I've found is that later in the game when you're building the type III facilities you need a shipyard to build them in a single turn. The production gained over the course of the game by having these facilities earlier outweighs the investment in having a SY on a planet instead of a facility. Taken in conjunction with the fact that you can produce ships and units MUCH more quickly, spaceborn shipyards don't make a lot of sense (note I am saying shipyards, not repair facilities).

Of course, I personally thing racial construction bonuses should apply to spaceborn shipyards. That would make your idea extremely viable.

The best test is to try the planetary shipyard tactic. No human player I've encountered has failed to switch to this methodology after it's been demonstrated to them in a game.

That could mean I play against weak opponents. What it really means is that 80 - 120 planetary shipyards in a game with a construction bonus dominates. Give it a try and let me know what you find.
