I'm really glad that you took the time to go on Wikipedia and educate yourself, but what you said,

So knowing this, is selling a hand drawn commission of a copyrighted fictional landscape any less illegal than selling an edited screenshot of a copyrighted fictional landscape? This is what you're arguing. Read your words. Also re-read the license.
Ever hear of what happened to No Game No Life's second season?

Literally first paragraph. Ultimately you can claim fair use all you want, but it essentially boils down to the opinion of the guy with the gavel.

The bottom line is, neither of us can actually answer this question, as it up to the jurisdiction of the copyright owner and a court of law.
Again I don't care what business you're in. You don't know what I'm in, and here on the internet you have absolutely no credibility just as I don't.
The reason I'm here giving you grief is not explicitly be a jerk, but because I have seen dozens of artists get scared of copyright infringement and going to jail or getting sued because they think some game company is gonna crack down on them for paid commissions. It wont happen. People in this few thousand post thread have asked for sources to be linked to the artists to give them the attention they deserve, and it's even kinder to mention they can be hired to do similar works, potentially more original.
I'm not here to convince you; I literally don't care about you. I'm here to ease anyone reading your original message and thinking they're going to get slapped.
Any artist's reading, you do you. The worst you're gonna get is a cease and desist, and if you draw lalafells lemme know. T_T
I honestly have more, but 3000 character limit.
