My main reason is is that I am sick of the white man guilt trip developers seem to be on these days.
Yes, colonialism happened, yes a lot of European nations did so, but so did cultures in the Middle East and Asia.
And colonists may have affected developing cultures for generations to come but it was not as if these were living in some utopia and harmony with another.
For me, it's about good writing. Part of why I love
A Song of Ice and Fire is because it isn't bullshit which romanticizes the nobility and treats it all as one big happy game. What I enjoyed about
Star Trek Deep Space Nine was it questioned the Utopian values of the Federation which were frequently built on giving easy answers to harsh problems or just dismissing the concerns of many RL peoples. I like complexities as well as honesty in my writing.
A Mass Effect game where you find yourself in a situation where you can, should, or want to take from less advanced civilizations like the "Avatar" movie but maybe with some nuance would be interesting to me. It's certainly more interesting than, "We show up in Andromeda and fight only BAD aliens."
Am I saying that colonists brought "civilization and order" to some backward lot? Well it is honestly not as if some of them didn't see their own advantages of the influx of new ideas and goods.
Honestly, that's a dishonest summation of the situation. Colonialism wasn't about the Natives, it was about the Europeans and the Europeans of the time knew that. The missionaries might have wanted to spread Christianity but colonialism was about gaining land and wealth with all of what Europe "brought" being devoted to taking. They knew it and didn't delude themselves about what it was about.
Certainly, Native americans weren't about being civilized as the Natives who assimilated into white culture, The Cherokee, were put on the Trail of Tears because they were Natives and had land.
Have respect for the fact Rhodesia was about setting up oneself as a God King. Not because it would somehow benefit the people forced to worship.
How does this relate to Andromeda?
It looks like the plot of the game is "go in, fight the Kett, find some worlds to colonize, everything is happy."
It sounds so...shallow.
