To be honest, in context of the games, there isn't too much of a problem with a Japanese company exploring using different ethnicity for their protagonists. Most of these characters on this list are from Capcom, Nintendo, Konami, and many of them are just pieces of an expanded universe. For example, Mike Haggar and Cody are in Final Fight, which is also a part of the Street Fighter Universe which has a lot of asian representation. Nina Williams in Death By Degrees is a spinoff of Tekken where there is obviously a lot of asian representation. In context of Castlevania and Ghouls N Ghosts, it's understandable within setting to have those characters are the protagonist, the fact that it is obviously set in Europe, and the cast of something like Castlevania are legacy characters usually related to the Belmont family (it would be really weird in this case if it was a japanese family fighting Dracula for generations). This post might seem like it would pick a bone with many people, but I think it is extremely disingenuous to say that japanese developers pretty much exclusively use white people. It would be a problem if they exclusively use it, but for a company like Capcom or Namco, their cast are actually pretty varied.
As far as generalization goes, Asians really do love white people and vice versa, although maybe not as much.
Also fuck this thought. To be honest, as an asian american growing up around a decent amount of FOBs, they have a lot to say about white people. Asian people don't automatically want to suck those white nuts contrary to what Neogaf believe. There actually is a lot of us and them mentality within groups of people.
