I don't know how a fictional place can be criticized for a lack of diversity.
Personally, I like big games to have a range of people and sexes from a variety of backgrounds but I don't think it makes much sense to demand that of something that was a person's invented setting.
You can criticize a class-based competitive shooter for lacking diversity in class types. You can also criticize a game with obviously human characters for a lack of apparent diversity, be it age, race, gender, background, and so forth. That doesn't harm the game, it doesn't defame or vilify the creator, and it isn't somehow better to ignore it completely because there are worse cases of the problem out there.
OP also isn't "demanding," anything so much as they are saying they'd appreciate more diversity. If there's one black dude, there would conceivably be other black people out there, and in such a deep game where you can cook breakfast and deliver it throughout town, or micro-manage your garden/love life/etc., it doesn't seem out of the question to ask for more character diversity, let alone to discuss it.
It's crazy to me that people think diversity as a concept can't exist in fictional settings.
