I seem to recall freeing slaves in Morrowind.
More like Morrowoke I guess
And the slavery in Morrowind was ultimately outlawed only when Argonians invaded from Black Marsh and started massacring every slaveowner, Haiti style.
There has never been a video game that was made worse by giving the player the chance to be John Brown
Hey Nerevarine, I think we're gonna have to kill this Telvanni scum
I made my Nevarine head of Telvanni, then located all the slaves and killed the people holding their keys and freed them. Didnt get expelled because Telvanni can kill each other without (official) consequences if you're strong enough.
Lmao got em
Oh no did someone get addicted to an amoral might makes right philosophy?
this is the way 
antintellectual fuckwits like this do not even respect or understand the art they tout as the superior old fashion. there is no serious analysis of morrowind that supports a 'non-opinion' or endorsement of slavery. it was just an accident that they included the option in the game to free every existing slave? that there's quests for an abolitionist faction, and abolitionist options in many quests? where are the commiserate pro-slavery options, dipshit?
Ignoring all the slavery is clearly the evil option. This chud yearns to be part of the trade himself.
all style no substance, the observation is that old quest direction was less upfront--true enough, but the notion that shears off the moral dimension of all the quests and writing is almost specious in its misunderstanding of the text.
Slips on generational Dunmer John Brown gloves 
I mean if star field was a canary in the coal mines.. look it’s not gonna be better we will be lucky if it’s a better version of Skyrim and even that is questionable.
I don't think anybody even likes Bethesda games for their genuine merits anymore. They're fundamentally broken in ways that people find appealing for some reason.
each bethesda game is now just the most recent and prettiest porn mod platform. Except Starfield was so underwhelming that most modders stayed on Fallout and Skyrim!
If Starfield is anything to go by the ways of resolving the quest will either be to leave the slaves where they are or purchase the slaves, with the slaveowners being unkillable despite only being in that one quest.
TES6 is going to suck because over the course of 20 years Bethesda has simply refused to learn anything about modern game design.
