It's taken a while, but I have finally gotten to a point in a game where I am ready to plan the last stages of the campaign. I have mapped the galaxy and found both AI homeworlds. I've captured several ARS' and a mark IV factory and have Space Planes, Chameleons, Stealth Battleships, and Bulletproof fighters in my fleet. I have also managed to repair two golems (Black Widow and Armored) and build a few Spire ships.
There's a planet I would like to take because it has two fabricators: Bomber Starship IV, and Warbird. I haven't played with either of these ships before and would love more firepower, but the planet is about as far away from the homeworlds, and any other important planet, as it is possible to get. It's four hops away from my closest planet and only one of the intervening worlds is Mark III. I could probably take a large force of Mark IV ships and rampage my way through those worlds with little difficulty.
My AIP is already close to 200, and would probably be bumped to 230-240 after I'm done capturing the fabricators. Would it be worth it? Are those starships powerful enough to make a difference or is my time better spent fighting my way to the closest AI homeworld? I'm playing difficulty 7/7, Vanilla AI if that helps.
