Space Age Venus and Jupiter Moon
You're probably not going to make it here (sorry). Coming soon though, don't worry.
Just took the first SAV sector
I'm PE with about 1250/860 att/def. I've 4 hovers of course but of note is that I've only 2 Turturrets (aborted Truth or Dare by mistake) and no Rail Guns (not sure how).
I've the usual other higher era stuff. The tail end of SAAB was a bit of a pain. You just have to suck it up and diamond heal a lot. Lots of mistakes involved where you retreat and have to diamond heal, making zero progress but learn from these mistakes.
One trick I've not seen mentioned is the injured Rogue, (90% health). Take one or maybe two along and I find they are attacked first, if in range, before your real unit. This can often make or break a result against units with Blast.
I trade a lot so have lots of goods up that end, and I do tend to be lazy and just negotiate when I see a difficult sector.
But as we know, this isn't possible on all sectors due to special goods.
I'm largely maxed out on att/def with my entire city space devoted to it. My only GB indulgence is HC and TT (which helps with goods). Still improving slowly but they will be small efficiency gains from here on.
I'm happy to contradict your above statement and to show it can be done . No doubt it will get pretty gruesome soon enough so I'll report back if I hit a wall. I'm thinking a level 10 Virgo Project may be useful at that stage.
