My game has close to a 1000 Dysons now. Its a shame its not more in between me and the AI home worlds in case something goes wrong.
I've reached the end phase I believe and I base this on how much waiting is involved. I own all but 5-8 planets in the galaxy and decided it was time to make a move on one of the AI despite hoarding my knowledge for the 50K award. I tried four times with a mostly mark 1 fleet of close to 10,000 ships and nearly lost the entire fleet because a single ion cannon and a ton of core tractor beams. Took out the ion at the cost of all 75 of my captured Z Electric bombers but experimenting with lightning warheads bumped up the AIP and the tech level of my waves to mark 2, which I had been careful the entire game to keep low with data center raids and the superterminal. I reloaded an older save because it became apparent that I had tried too early and the alerted Core world was reinforcing with core ships at an ugly rate.
After achieving the 50K award, I reloaded the game. My new plan is to max caps of raiders, bombers, dreadnaughts, and the spire line but this is going to take a very long time. My defenses are however stable enough that I don't have to watch my home system during cpa's or waves under a 3,000. It was at this point I realized I wasn't playing the game because I spent most of the time checking build times or being tabbed out surfing the internet while I waited. Each Mark of dreadnaughts allows for 30 ships for a grand total of 90 but they will take a long time to build. I upgraded raiders and bombers to mark 3 and so with advanced factories going I should be able to get a fleet of mark 1-4's. However running all of this at once is giving me resource problems despite having 6 Zenith Power Generators, 3-4 gravity drills I made sure to capture, and owning 30 fully developed planets. I went with raiders since they have immunity to tractor beams and are strong against frigates (the ai is reinforcing with tons of Core frigates). The bombers will be needed against the Core Shield but I will need to find a way to get them around the tractor beams.
I have access to four different golems but I don't think they would help solve my problems since what I really need to do is upgrade my fleet of spaceships, even though I could activate one rather quickly. While I appreciate the recent changes to golems, I don't think I'm all that tempted to try one yet. Reinforcements trigged by the presence of a Golem reflect the tech level of the planet you are invading so I think a Golem's usefulness will drop off proportionally along with how high the tech level is.
I'm not sure what all I should be doing right now or could have done differently but I have a lot of waiting to do in this game now and the change of pace from what I was enjoying earlier is a bit annoying. I could have been building mark 2s and 3s sooner but thats all I can really think of.
