Even though I haven't ever built any of the 3 Temples, the Temple of Righteousness of the Good Alignment looks the best. Tourism is never big enough a deal to make the neutral temple worthwhile and the evil races will probably be too busy killing each other to even bother trading.

Good Civilizations get a 25% boost to trade income with other Good Civs, and are supposedly more peaceful. So if you're a Good Civ, you could send all your trade routes to another Good Civ, cover the trade route array with Economic Starbases, upgrade those Starbases with Trade Center and prerequisite modules, get an Economic Treaty and Alliance with that Good race, and build the Temple of Righteousness and Galactic Privateer. That would be the ultimate trade system. Perfect for Rare-setting galaxies if you had the time to build such a thing.

I completely agree. The game would be very boring if I always had the same building type available to do a job. When you are very broke those 'useless' buildings can come in handy since they give a smaller bonus for a smaller price.

You might also note that Stardock is basically doing something never done before. They are letting the fans rewrite the game. They actually listen to our ideas, question us about theirs and then change the game to match our desires when they can. Some of those useless buildings came out of that process. That being the case, I say they can strike out a few times.

Perhaps if you think hard you can devise a strategy that can make use of some of these things. The game has so many possibilites that it is possible you never played a game with settings that make good use of those particular buildings.

One of the problems with the buildings is that you don't obviously know their
exact effects unless you dip into the .xml files, but also you aren't told whether
the effect (like increasing morale or birth rate) is just for that planet or all your planets.

We need a Galactopedia for DA. Someone mentioned how the program might be modified to work with DA. Don't remember how.
