บท 2: Question for you guys

For the few people who read the first chapter and liked it, I would like to ask something. I was thinking about adding another universe to the book, because honestly, I realized that even with several games, the RE universe isn't that big. Do you think it would be good for me to add, for example, the Marvel universe, DC, Harry Potter, etc? I won't add all of this of course, just suggestions.
