It would be neat to colonize Andromeda, then i could indulge my minor sociopathic needs X)
Time to make considerable decisions for the greater good of our people (Team Milky Way!)
And for once we have a valid reason to do so

so let's make the most of it.
And we're not
bad guys in my pov X) , our own people's survival is at stake if the leak is true.
I'd be really fond of the prospect of working with the other Milkyway species as one "nation" towards a common goal, and even be able to identify as a Milkyway people rather than merely an human (I'm surprised myself because I usually play as a pro-human, not xenophobic but still trying to prioritise human interests before anything X) )
It would give me such an uplifting feeling ><
-Even if it means wiping out Andromeda aliens if they don't agree with us, so we can find a new home- XD
I think there'd be enough space for everyone, the new species can't own EVERY SINGLE planet since Andromeda is supposed to be bigger than our galaxy.
They have no claims on planets they haven't discovered yet, or even weren't aware of X)
If they want to argue about it (something I'm sure they would do 'cause ego) just nuke them.
By colonizing people I don't mean to assimilate the Andromeda species and enslave them. That would be kinda disturbing XD wait, at a same time it'd be cool to have minions. :| It would be a new level of crazy
I know it would bite us in the ass later tho.
If we do colonize Andromeda, I hope they won't give us a moral lecture and try to make us the hero of the new galaxy who units all the aliens :/ it's going to kill all the fun.
I don't want to be a galactic hero. Just a hero for the MW people and a super villain for the others.
