Pokemon literally clears every gaming franchise on the planet, just to put things in perspective.
I want to explain something to Nintendo fans that seem to live in some delusional mindset where they think Nintendo won't be impacted at all by GTA 6.
GTA 6 will be the biggest launch in entertainment history, period. Rockstar will be spending close to a billion dollars on marketing, you are going to see the game everywhere before release and even after release. It's going to be all over Tik Tok, streamers, youtubers and website publications will be covering it non stop, word of mouth will be all about GTA 6.
Now obviously Nintendo diehards will buy Nintendo games regardless of this but Nintendo isn't just thinking about them, they have to market to people outside twitter, reddit, gaming forums bubbles etc. Now you can't do that when a single game is dominating the conversation everywhere, this is the part that Nintendo fans fail to realise, this is why publishers would rather risk cannibalizing each other in September than going head to head with GTA 6.
Xmas is the most important time of the year for Nintendo and they will have to spend three times as much in marketing to even be close to piercing through the noise of GTA 6 especially in the U.S. their largest market. Nintendo will have to release something for the Xmas period no doubt and I am sure whatever it is it won't flop but they will definitely be impacted in some way by GTA 6 despite it not even being on the platform because at the end of the day attention is the fundamental currency of the entertainment industry.
Something to think about.
