Interesting, and totally different from my view.
I'm pretty sure it is because I've been doing it for so long that I have an 'old style' way of looking at things.
Which means it is me and the AI, nothing else.
So all the hybrids/exo/minor faction stuff you have enabled I would play with them disabled. (I'm not going to get into a relative difficulty argument, some of the stuff makes the game easier, some makes it harder and I'm leaving it at that.) Call it how I prefer to play.
The only thing I actually disagree with is AI Auto Progress must be at a minimum 1 per 30 mins. (For the record, my current 10/10 does have it disabled but I am experimenting with starships and did not want to be rushed.)
The other two big difference are AI type, this stays at "Random All Non-Tech" always. (I do enable "Reveal Random AI Types" however.)
The other is I don't pick my bonus ship type, I pick my map (Lattice, 80 planet), click the "New Map Seed" button 2 or 3 times, then I hit 'Start Game' without looking at the map or starting ship type.
Random AI types, random bonus ship, random map location. This is all to keep the games feeling different. The way the Scorched Earth I'm fighting is cramping my strategy is very different then how a Spire Hammer or Train Master would.
Not picking the bonus ship makes sure I get a different one every game and not picking a super defensible map location also keeps things different.
Does this mean the RNG sometimes hates me and I lose the game before I start? Yes, but it makes each game at least a little different then the last.
So, to summarize:
All Expansions Enabled
Single HW, no champion
Diff 10/10, Random All Non-Tech
All Ship types enabled, including CSGs.
All minor factions and AI plots disabled. (Except Reveal Random AI Types). So no golems/spirecraft/fallen spire stuff.
Normal Caps, Normal Combat Style.
Default Fog of War (Full Fog of War I believe)
All bonus ship types allowed, but no picking ship type or map location, you hit "New Map Seed" and "Start Game" without looking at the galaxy map generated.
Actually, looking at that, maybe calling this the "Pure" play style is better? It is just the player and the AI, no distractions.
Now, if this meets the bug report standard or not is up for debate, there is a lot of game features I turn off, but I've been playing since before those features were released and while they are fun, for me a 'true' game of AI war does not have those features in play.
(Let me restate that this is just my opinion, there is no objective 'true' way to play AI war and this post is how I play, not how you should play.)
