About this one:

No Mercy

Assimilate the Sisters of Mercy minor faction by invading their system

In this galaxy settings you can found Sisters of Mercy. You'll have to research a bit, but it's not a very big galaxy:

Shape: Spiral - 6

Size: Medium

Density: Medium

Generation Seed: 4809

Resource abundance & Curisity frequence at Normal.

Difficulty: Hard.

Rest of parameters set as preset, normal, or whater is close to not modifying them

regarding my last to do achievment - Home is where the heart is, here is what I have to share:

I found boreal to be the one most elusive planet type, but it's pretty random, Huge galaxy on high density should cover all your colonizing needs.

If you want to be thorough, here are some tips I thought of afterwards and might make it even easier and even further improve your odds of success:

• I suggest placing underpowered custom races with various starting planets in a clustered setup so that you may invade and conquer in early to save time searching for them - those little more rare would then probably include all the fertile alternatives like boreal, ocean, forest etc... you can even go full 12 players and use the military law to maintain super high approval
• Many minor factions also helps since assimilation enables you to obtain planets at range without colonizing and thus creating a new point of origin for scouts and colony ships.
• Be picky about systems, do not overdo it or opt in for expansionist trait in order to avoid overcolonization
• If you are going to go two players or eliminate others in early I suggest meritocratic pop combined with emperor trait for cheap and frequent influence buyouts, but then anything works

Here is a planet type checklist for your convenience:

Atoll
Ocean
Boreal
Forest
Terran
Jungle
Meditar
Monsoon
Tundra
Arid
Snow
Savannah
Steppes
Arctic
Desert
Toxic
Ash
Lava
Ice
Barren
GasTemp
GasHot
GasWarm
GasCold
GasBurning
GasFrozen

best of luck!

Think of it as a race and an optimization problem, that's pretty much what the game is about anyway, so it's not that different from the usual gameplay. =D

Well, finally get the ones remaining.

If you want to get the "Ying and Yang", and "galaxy together" quickly, my recommendations, are use @Tyrenium seeds, put game on sandbox difficulty and send a explorer with seeker hero (fortunately for unfallen is the starting one) to send probes everywhere. While doing this stockpile influence, and once you localized the system with the minor go straight it. Abuout unfallen a fleet with 10 vineships equipped only with an engine and the entwinning module is highly revcommendalbe to get to the system quicker, as you'll need to entwine it before assimilation.

For "hearth is where home is", I found best way is to play in a very big galaxy setting, to ensure there are all planet types. Then print one of @CyRob's ITER planets lists to check what you have colonized. Also playing Sophons in sandbox difficulty may be useful, because AI wont be at your pace, and they got a pretty big movement bonus from scy law, that allows you to send colonizer far and fast.

Also for all this three achievements, if you only want the achievement and don't mind about this game (for sure your play more later), not only put the difficulty on sandbox, but also pick only one opponent. This will ensure a free galaxy for you to get quikcly to the desired minors/planet types.

A final warning: doin this that way ensures the achievement, but this gameplay will be boring. At your own risk.

Did someone come up with a seed yet? :-D the 76/77 achievments is annoying. =D

I expect it will count if the terraforming happens before you acquire it, but only way to be sure is test it I guess.

I wonder if you terraform the planets, lose the system and then regain it the terraformed planets then count?

Colonize one of each type of planet in one game - by C0ldSn4p

What counts towards it:

Colonizing a Planet in a new System with a Colonizer, Celestial Vines, Arks etc...

Colonizing a Planet in a Colonized System using the System Production Queue 

Receiving Planets through basically any mean (quest, assimilation, invasion etc...)

What does not counts towards it:

Terraforming an existing Planet

I hope this helps :)

Ah, that's where the misstep was. I terraformed to get a terran planet, but that doesn't work. Thanks. 

Although, if an AI terraforms a planet, then you conquer/assimilate it, does that count or no?

Could any of the devs clarify what is exactly meant by that achievement? Because if you have to settle those types of planets from scratch, it's a killer achievement, due to how difficult it is to find all of the different planet types, and uncolonized at that. 

Man tracking down all those gas giants was a pain, I never noticed there were so many before.

Yeah not a clue, some people according to steam statistics have it, can't tell why. Probably got lucky with gas giant spawns, just play ridiculously huge games for a while and probably will come by itself eventually. =D

Thanks again!

Here is another nice galaxy that has both Mavros and Eyder:

There are two rings of systems in this galaxy. You have to send out quite a number of probes to discover all of it.

Thanks!

Sorry to necro this thread, but I was trying to follow along w/ @Tyrenium first post for Back to School.

When I put this in, I don't get the Academy to the right of my starting position. It's not in any nearby system, actually. The AI always gets to it first, wherever it is. Are there other settings which need to be adjusted?

I did set up a game with some randomly set variables (playing as Unfallen) & I found the Academy to the northeast of my starting position. I sent a fleet to the closest planet I can get to w/ a hero, then launched a probe at it but it doesn't unlock Back to School. I loaded to an earlier turn & tried instead to put the hero on a Vineship, which gives enough vision to see the system but still no luck. What's the trick for Back to School?

I have no mods installed, if that matters.
