"Battle Royale" conflicts with an Epic IP

Yeah, I confuse trademark and copyright all the time. They have a copyright on the game “Fortnite” itself. I don’t see one for “Fortnite: Battle Royale”. If it was “Fortnite: Battle Royale”, I would understand not being able to use “Battle Royale” in my title and the confusion (if any) my title would cause in the marketplace. My best friend is a former IP lawyer, who now does software development. I have already sent details about this whole thing to him so I’ll see what he has to say in terms of trademark, copyright, and IP.

And that is fine about their right to request a name change. However, I don’t understand why it comes 3 months after my first review and in my 3 previous reviews, there have been no problems with my title. If my project was passed and put on the marketplace before Fortnite’s Battle Royale release, would they have forced me to change the name of my already released project? Have they forced the renaming of already released marketplace assets because of Epic IP in the past? This is all hypothetical and doesn’t apply to my situation but is definitely something to think about. What if I released something called “Card Game Template”? Can I not have “Card” in the name because of “Cards” in Paragon? You might laugh at that question, but it is on the same lines when regarding my title.
