Would it be worth to nuke 2 IV planets owned by the DIF 10 AI and capture another 6-8 (mostly owned by the DIF1 ai) to create a complete closed off side of the map, with exactly 1 (yes 1) front (1 wormhole to enemy planet) literally about 12 planets all under my control (and with that, no more spec ops posts so no more patrols in this entire "arm" of the galaxy.
Hard to say. That will skyrocket the AI Progress, so it depends on the specifics of your map. Sounds dubious to me, though. But if the resources are worth it, then that's cool.
- Most importantly, does nuking change awareness in 1 or 2 hop away worlds? Because thats the other IV world ;p They are both in the way of unification
Any AI planets that border planets not controlled by the AI are on alert. So if you take control of one of those planets, or nuke it out of existence, or just wipe the AI off and then don't do anything, then those next in line will be on alert.
- The problem is, i calculate a progression of 350~ for the entire thing, and the DIF 10 AI is already tech 2 (i am at 52 progression) the DIF 1 ai is at tech 1
Yeah, that might well bump the AI 10 up to tech 3, and the AI 1 will definitely go to tech 2, not that you really need to worry about them. There's not one solid answer to this question in my opinion -- it depends on your playstyle as well as a lot of factors of the situation. If you think you can pull it off, go for it, but it's definitely not without risk.
How bad does Progression of 350 make my stand at a single front with 1 DIF 10? After i capped those planets i should have about every ship type unlocked including all MK3s, but the price is that there is a big chance that there is no datacenter/research lab or anything else in those worlds. So i basically pay 350 Progression for uniting all my worlds to 1 frontal world - technically that sounds like a superb deal, i could pack one world full with all the turrets i'd ever need.... and just advance for deep raids and scouting expeditions beyond that.
All true, in general. Of course, the AI Progress also affects the reinforcements, as does the number of planets you take from the AI, so you might find yourself on the business end of some nasty cross-planet raids in addition to very well-defended other planets from the AI. But by the same token, if you have all the resources and stuff you need, maybe that won't matter. As long as you can get a large payload to the AI home planets without setting them on alert too early, you're golden. If you can't do that, you might want to focus on advanced research stations first.
Not to mention i'd be swimming in resources (they are really scarce atm ,p)
That certainly does always help. Especially if they are going to be as well defended as you think they will, that will free up a lot of your forces for offense, which is huge.
