Horizontal Integration - Don't harvest ANY primary resources (ie, the one with resource pips) as non-scientific in a won ranked match. (If that's too hard, only harvest from resource pips no higher than low.)
Horizontal non-Integration - Don't sell any primary resources (including power) and win.
Monopoly Man - Purchase 200k worth of underground nukes in a won ranked match.
Why we can't have nice things - Successfully dynamite offworlds 5 times in a won ranked match.
The Invisible Rocket - Build the first not-goonsquaded offworld in a ranked free for all match that doesn't get dynamited during the rest of the entire match. (Dynamite must be available on the BM)
Swiss Army Robot - As robotic never make more than 2 of any secondary resource building per resource type and never more than 1 primary resource harvester per resource type. (This is supposed to make use of the robotic bonus and power should probably be excluded from this)
Did you really really need that? - Get a goonsquad you placed on a tile that doesn't belong to you triggered 3 times in a a won ranked match. (Mutiny + Goonsquad)
The Way of Cube - Win 32 times (not in a row) after founding with 32k debt.
Rapid Acquisition - Win a ranked 1v1 match before day 4 through majority buyout.
King of the Hill - Win a ranked 4p FFA match with 3 majority buyouts.
Imo all of these achievements need to be linked to won ranked matches because they're trivially easy to accomplish in custom matches with friends but not as easy in ranked matches you have to win in order to get them. By making the requirement a won ranked match they'd actually be hard to achieve and thus actually worthwhile and brag-worthy. Alternatively there should be ranked versions of these achievements. I personally consider any other type of achievement pointless. And finally, you probably should be able to get these and other similar achievements multiple times and be able to show to other how many times you got them.
