Inspired by a couple recent threads talking about the Scorched Earth AI type, I decided to go and play a game with both AI's of this type.
This requires an unusual strategy to say the least.
So far I'm doing pretty good, but I did only go Diff 7.
Because I put myself up against 2 Diff 7 Scorched Earth types, I turned everything else off except for the Zenith Trader so that I could get a Zenith Power Generator.
With the scorched earth type, you can't destroy any Command stations because they then interrupt supply so the only knowledge you will gain will be from the systems adjacent to your homeplanet using Mk III science labs. Because of this I went with 3 wormholes connecting to my homeworld to get a decent chunk of knowledge but not make my defensive situation too tough.
I then established outposts in each system adjacent to my homeworld to build energy reactors so that the efficiency penalty doesn't cripple me. The science labs also get build so I can get the knowledge. The outposts are located so that any ships incoming from further away then one hop have to go through my outposts, this lets me destroy the warp gates so that I have a system for defensive depth if I need it.
So far I haven't, because I'm not destroying any command stations AIP is only 57 at 7:43:00 gametime with an AIP progress of 1 per 30 min. That means like only 50 ships in a wave.
The outposts are now up to over 100 units each, mostly turrets, and pretty much invulnerable because so few ships are being thrown at them with this low AIP.
Once all this is done, I then turn to my offensive fleet. There are two things that will make this possible. Engineers do not require supply so I can repair my fleet and there is a Mercenary Enclave Starship you can build without spending knowledge.
The Zenith power generator and Mercenary Enclave Starship alone are 1.5 million metal and crystal, it takes me several hours gametime to build these two units with only my home system for resources. I was sitting up at +10 speed and Frame Skip 10 for most of it.
I then build the rest of my offensive fleet that will go out and attack.
The basic strategy is that my Mk I units will break me into a system because I can replace them outside of supply with the Encalve starship and the sieges will clear the system, except for the command station with the rest of my fleet along to break the tougher systems.
So far, this has worked on everything I've encountered, but I haven't run into a Mk IV system yet. I expect to soon as my offensive fleet is 8 hops from my home system at the moment and I'm about to start my attack on the next world out.
Galaxy map attached. My homeworld is selected and you can see my offensive fleet in the bottom left about to curl around and up to where I'm guessing the homeworlds are.
Overall, an interesting game but it's way too slow because with only a single system for resources you just don't have enough.

edit: Ouchies. That next system out had 2 ion cannons. My Mk I units have wiped 3 times now, this strategy isn't holding up too well as I hit the tougher systems.
