No. It's not silly to argue that there's a connection when Mobius is LITERALLY USING THE DATA FROM THE FINAL FANTASY VII REMAKE. It's not a thematic connection, or even just borrowing the character. The FFVII event things are LITERALLY ASSETS FROM THE FFVII REMAKE IN DEVELOPMENT BEING USED IN ANOTHER GAME.
To reiterate: The people working on Mobius didn't just design their game's version of Cloud & the other FFVII stuff, they LITERALLY TOOK ALL OF THE FFVII DATA DIRECTLY FROM THE REMAKE.
