I'm not pointing fingers of judgement, so please, calm down. What I'm saying is that, like always, people with lighter skin tones have it very easy, while people with darker skin tones have it more difficult. In the game, people with light skin tones (whether they're white, Japanese, Korean, Chinese, or any race that has the potential to have light skin) can start up the game and immediately, they have their skin tone. No work, no effort. They can look at their character and say "Yep! That's me!" But people with darker skin (even Japanese, Korean, and Chinese people -- because they CAN have dark skin) have to work to get their mayor to look like them. Is that racism? Short answer, yes. Because it's not equal. People with light skin don't have to do anything for their skin tone, while people with dark skin have to work hours and hours to get their skin tone in the game to match their skin tone in real life.
If Nintendo really put profit before people (and they probably do, considering they are a huge company), that's morally wrong and, yes, that's their problem, but not calling out the problem won't make it go away. They're not going to put a different skin tone option into the next AC game unless people bring up the topic of "Hey, why is everyone so pale?" I'm not saying YOU are racist, and I'm not even saying that Nintendo, as an entire company, is racist. I specified in my original reply that it's, in the least, forgetting and exclusionary.
However, if you are willing to say "We can't add a better race option because it destroys the ~atmosphere~ of the game," instead of reasoning that having a selection of skin colors on-screen long enough for the player to pick theirs is a decent and acceptable option, that's a little racist. It would be two seconds out of thousands of seconds that anyone would be playing the game. White people and other light-skinned people are not and should not be the default option. That's why I would never rate any AC game as 5/5 or 10/10, because it's exclusionary in both the aspects of race AND gender. But the gender thing is another discussion entirely.
Basically, what I'm saying is that if Nintendo can't be creative enough to add questions that could determine a player's skin tone, they can just add a screen so a player can choose. If they can't do that, they're racist. And if you think they SHOULDN'T do that, you're not immediately racist, but you should definitely think about WHY you think that.
EDIT: Also, "But thinking that they're gonna go out of their way to make a few more people happy with one little quirk is just unrealistic" is really offensive. Someone's RACE is not a "little quirk." It's their race. Come on now.
