Minorities: It's an Eastern European medieval style setting, I think they get a pass there. More generally Geralt stands up against racism (or can).

They could, however take on board the example given by The Witcher 3's excellent side content.
That raised the bar for RPGs and I hope that does influence what happens in MEA's huge worlds...
Actually 2 points: First you right, plus Geralt as Witcher is part of the minority that normal ppl hate. Like it can be see during the game.
And second, really Witcher 3 didnt raised the bar for RPG it doenst do anything new that older RPG havent dont back them. And actually ME games have more interesting side quest that Witcher 3 since Witcher use the "contract" side quest alot and become really repetitive.
