...ugh...Play Morrowind. It's extremely cheap to buy these days, and it's a much more fulfilling game than Oblivion. If you can get passed the combat system, it's very much superior to OB in most respects. Plus, nearly every PC can run it quite well, with mods too.
But yes, it seems any race can be a slave in Morrowind, and ONLY Morrowind. Slavery is illegal everywhere else.
When I played Morrowind, I never had such an experience.
Suddenly there were no walls. Suddenly I could do whatever I could imagine the system allowed.
It was, as I said to people I tried to enthuse, like I played a game made by people who love games, instead of people who love money.
I could write an actual entire page about what Morrowind did well and later installments did not.
The best example however is this:
In Morrowind I could permanently make peaceful a hostile Ashlander by calming him and getting his disposition to 100. Perfect for a diplomat Nerevarine.
Try that with the Forsworn.
This freedom is wholly lost.
Skyrim is
just a game like all the others.
Its not a world anymore, its a linear game you play how you are told how to play.
At this point I love the lore. The games are secondary to me, because since Oblivion they really are not that good.
