Should I change my book title?

I've been nghề viết văn a book called "Soul Fighter" and planning to đăng lên it, until I googled the tiêu đề and recieved a lot of results. But instead of the S.F. being a book, it's a dreamcast video game, I believe, and it probably has a completely different story, but I'm still wondering if it would be a big deal if I don't change my book's title. Should I?
