There have been many conversations about the all male, all white cast of those books. Perhaps if you regularly visited forums about fantasy novels you would have seen people's reactions to the book, and especially its legacy. Not everyone is happy with the white male protagonist model that permeates the epic fantasy genre.Olas said:
The movies were altered to give a larger role to Arwen because the movie was so packed with guys. She never saw combat in the books. That scene with saving Frodo at the river was altered for the movies. That was a male elf that we only meet once in the books. She wasn't shown in flash backs and dreams. That necklace that she gave to Aragorn as a symbol of their love or whatever? Never happened in the books. You just meet her at Rivendell, find out that Aragorn loves her, then later they get married. Originally it was just Eowyn that had any prominence as a female fighter. And while Gladriel never saw combat in the books, or movies, she was still played up to be powerful and mysterious. The franchise even made up a female chracter for the Hobbit movies. If there was no problem with the books being the way that it was then I doubt any of those changes would have been made.
But the biggest problem with your LOTR example is that LOTR featured nine white guys that weren't carbon copys of each other. They had differences in height, build, weight, race, personality, and motivation. And that makes a big difference. Because if you are gonna have a sausage fest at least make the characters distinct. It's not like there is anything wrong with having a story all about male characters. It's just that it's overdone so people want something a little different. But a good all male story will still be welcomed because it's good.
Ubisoft didn't design a game about four white guys. They designed a game with one white guy, and chose to make a multiplayer mode where everyone plays a color coded copy of the same guy. There would have been less backlash if the multiplayer at least had four different white guys. Or if they had advertized their game differently(because people wouldn't incorrectly assume that the story has four protagonists like the trailer and disk cover suggest). And there would have been less backlash if they had just explained how their mutiplayer functioned, instead of putting their foot in their mouths by explaining that they wanted a female chracter but couldn't because of a lack of resources. I'm not sure what's worse, the idea that they really did want a female chracter and had to drop it, or that idea that they hadn't planed for one and lied about it to make themselves look like they at least thought about being inclusive. I am gonna give Ubi the benefit of the doubt and assume that they really did want a female chracter. But if that was the case they probably should have avoided talking about how they wanted one in order to avoid looking bad. They should have just played up the features that they did put in the game, like a proper PR department would have.
