Prelude: Screenshots speak a thousand words.
Couple of things: 7.0 is "normal" and should be winnable provided you already know the game well. But it takes either a lot of reading or experience to know this game well. So if you are losing and are new it may not be just you, you just may not know everything so are suffering.
Secondly, what was your AIP like? Or perhaps, what was the number of the AI progress?
Thirdly, what kind of AI type were you playing against? If you picked a random one, you might have gotten a very aggressive one.
Fourthly, screenshots speak a thousand words.
Prelude; Do I really need screenshots to display the aforementioned 500-600 AI ships? I don't need a thousand words to describe my problem. A huge blob of AI ships trashing my perimeter defences, outrunning my fleet and blowing up my command centre (I think you get the idea), is that really screenshot worthy?
The game classifies 7.3 as normal (I've beat it on 7 and wanted to try something a bit harder), above that is getting into hard. Also, did you read my post? I said I wasn't new.
Secondly, AIP was not very high at all, it would have been above 0 if I'd blown up a command centre before I get ganked. Which leads on to your third point; the AI was indeed on random, however, it has occured - more often true with aggressive AI's- also with any AI that launches raids. I'm talking about combined AI raids, they both occassionally raid at the same time and while one AI has had a manageable fleet (only 200 ships or so), the other attacks at the same time with over 400.
Fourthly, I read
your post so I answered it the first time. Don't patronise me.
This doesn't happen every game so I suspect I may just have been unlucky, it's just happening often enough to be a problem. As far as AIP goes, I'm lucky if I've gotten as far as taking one other planet. So the AIP is only at 15 or so (command centre + warp gate, maybe a special guard post too) but it's never been higher than 20. Also, it's actually waves, not border aggression and I'm not playing with any options that strengthen waves.
Although, something I have observed is that, there is an absurd amount of neinzul youngling ships in these waves. I'm not playing with neinzul enthusiastic AI but these ships have been present in every incident so far in huge numbers, comprising maybe half of the enemy ships. Not sure what to make of this.
I'll give the extra shield generators a try and see how that goes.
