Can we just ban the term "GTA" from this thread? It has nothing to do with Switch 2 really, and has even less to do with Final Fantasy potentially on other platforms like Switch 2.
There is no brand in the industry that stops other hardware brands from selling, Zelda/Mario Kart/Animal Crossing doesn't stop Playstation from selling, GTA/COD/Madden NFL didn't stop the Switch from becoming the best selling hardware likely ever, Spider-Man/Last of Us/God of War/etc. doesn't stop the PC, none of the above stop mobile gaming from being massive either.
