Like the topic says, I am looking for opinions on planetary defenses.
Currently they seem to be not very useful given their (relatively) extreme manufacture/build time, and most wars will (sometimes anyway) be over by the time the thing sees an end to construction. Key worlds will be siezed and fleet fights will be exchanged in often fast and brutal fashion, often resulting in planetary invasions within a few turns of a war being started - the things never get done in time unless rushed. Even if rushed it's usually better to make a fleet to avoid having to defend against a planetary invasion. (The offense bonus is staggering most times, especially if they use a special attack)
My proposal is this - retool the things. Somehow. Make them cheaper, make them a super project, give them an aura radius, something. Anything. I like the concept of planetary defenses, but they need something to make them strategically good to use, like military starbases.(which are a good example of valuable static defenses)
Thanks for reading.
