Seen a few comments on the board that suggest certain things
that are not true. Im not saying that using hordes
of starfighters to beat masochistic doesnt work(though I
think someone is abusing a fleet stacking bug?) But it
certaintly isnt the only way to win.

I will state upfront what lame things I do do.

I use ctrl-n alot.
I will on occasion go back to a saved game, though not often.

Tiny abundant map:
+2 speed +20 soldiering populist.

Colonize 2-3 nearby systems while teching straight to
diplo and then impulse while hero searches for +weapons.

I purchase the cships to claim systems so I can tech nonstop.
I do not colonize the 2nd+ planets in a system until later.

Once I have impulse, I switch to 100% military production
and build 2-3 transports and colonize the rest of my planets

I take my transports and hero and take out the nearest
major. If a 2nd major is small or my hero got lucky with
+weapons I can sometimes take a 2nd major. Otherwise
I switch to 30% social 70% tech and build some soil,
habitat(I of course do a lot of tech trading) and
entertainment.

With the 70% tech I research towards frigates. Once I get
frigates I spend 100% on military and build a ton of em.

I then take out the biggest AI first followed by the 2nd
and 3rd etc, until only the Yor are left

My general strategy is to move enough frigates/transports
near the enemy to take all their systems in a single turn.
With all their systems gone in a single turn, their generally
larger fleet disappears instantly without firing a shot.
They will easily also have frigates by this time as well.

Once my fleet is pretty much unstoppable, I switch the
production to constructors and capture all the resource
sectors and build up my best sector with a lot of production
increasing starbases.

This, btw, is where the game switches from being fun and
enjoyable to being a metaverse mastarbating boring toil
that involves no skill whatsoever and is just a formulalic
process.

Anyway, I am at 30/30/40 or so building morale/pq
improvements, constructors and researching techs that have
wonders/tradegoods. The sector I am building up with
production starbases will then start building these wonders.
Incrediable Yor are still quite good at building wonders,
so this is a bit of a challange.

Anyway, I will then culturally flip the Yor systems until
they have none left. I will have prepared a 13 pq system
with 5 million pop off in some corner somewhere and then
donate this system to the Yor(their pq bonus will make it a
15 or 16 system). They will no longer build anymore
wonders I will also have prepared about 9 freighters at
this system to set up some traderoutes.

Anyway, once all the techs that result in wonders are
researched I flip the tech chart to show the lowest cost
first and balance the spending to barely get the cheapest
tech the next month with the rest going to social. Some
planets that have half built constructors I switch to colony
ships and colonize all the 13+ planets. I might also
purchase some to get a remaining few.

As the techs get more expensive, I keep upping the spending
to maintain the next month to new techs idealogy.

At some point I lower my spending so I can buy social
improvements at the slower planets.

Around galatic creation, most planets are done building
morale/pq improvements and I pump my tech spending to 100%
and go for final frontier/beyond human(tech victory off)
Even with 100% tech these techs take some 40+ turns each.

So I just hit turn 80 some times, buy an excalibur and
some combat transports and end the Yors existence, game over.
