Have you ever played a pirate game? A fair amount of slavery on the high seas during the Age of Sail / Exploration; some pirates were believers in freedom, but not all. With that said, why would they ever use pirates in medieval fantasy games?

Have you ever played a vampire game? You know what vampire thralls are right? Wait, they use vampires in Skyrimn too. Hmmmm... problematic! How could anyone enjoy that?

Have you ever played a game in ancient Rome? Ancient Greece? Ancient China? Yep... same in all.

My point is simply this:

IMO your issue with the setting of New World -- and the way you expressed that issue -- says more about you than the game.

If you want to judge / disqualify games due to "bad things" that happened in tangentially-related real life history, you'll be disqualifying quite a tremendous, tremendous list.

But please refrain from making gross generalizations about vast numbers of people.

Amazon too poor and incompetent to have their own client? Yikes.

Do they also have some kind of streaming gaming service like Stadia etc.?

They'd probably want to invest more on that... but I am unsure how suitable a (free-to-play?) MMO is to such a streaming service which costs the company a lot of money to keep up, so naturally it can't be a home for free-to-play games where people by default are not willing to pay monthly fees (after all, it wouldn't be free-to-play then, right?), and where microtransactions are not guaranteed to bring enough money in (which is why I think e.g. Valve has lost interest towards Team Fortress 2).

Well, I guess you're right considering the official historical conventions. But those were still "dark ages".

Can't deny that, but they usually had bigger problems in the new world, at least initially. As in let's not starve now, hunt witches later.

I was gonna clean my room...

One thing that intrigues me about TNW is the fact that when you level up, you get points to spend on your attributes. This is different from most MMOs where you just get flat stat increases with level up, but most of your stats come from items.

No clue, don't think so.

A client is/was pretty much standard for MMOs. Limiting yourself to Steam is a pretty stupid thing to do. I know some use both, so it's probably compatible too.
