Hey I play this game and you can make characters and I realized I almost barely make characters that are a different race and I really want to make different characters but I’m afraid other people would think it is wrong if my Oc is a different race compared to me and think I’m a bad person. Can I do that?

It shouldn't matter what OC's race is, weather it's different from yours or not. You can make your OC look, act, and even sound completely different from you.  Take my OC's for example, I'm someone who loves to stay indoors and binge watch anime, but that's just me.  Two of them aren't that much different than I am, the other is like my total opposite.  I'm Poly- meaning I speak and understand over 4 languages(even if it's not fluent) -, my OC's aren't.  Two OC's of mine are like Japanese, the other one's British, and I'm a Salvadorian-American.

My point is it shouldn't matter to you what other people think.  Just because you make your OC's a different race from you doesn't make you a bad person, if anything it makes you a better person because of it.  It shows that you are a person who doesn't just think about one race and doesn't think that any race is better than another.
