There is not a major reason to purchase a PS5 is what I meant. All the games on it are currently found on the PS4. Is the experience enhanced on the PS5? Yes absolutely but I don't think that is what is driving up demand. I think the reason why PS5 is selling so well is a combination of an increased appetite for gaming due to COVID and the belief that the system will bring next gen experiences in the future, which it will obviously do.
I just think Sony, and especially in Europe, has always been able to generate demand without major exclusive releases (at least since the PS2) as opposed to Microsoft and Nintendo. There's just a bit more belief that Sony will get the games there. It's absolutely no criticism to the console, the PS has that mojo that the others do not.
I think we underestimate the value of a cross gen titles. They're not exciting from our perspective but no prior console has launched alongside so many of the newest entries in some of the biggest IPs in the world like Spiderman/COD/Fifa/AC etc. Having one or 2 big exclusives of a specific genre and appeal is hard thing to compare to having a dozen highly anticipated games. Of those titles, sure you can play them on your current system, but how many people like the idea of playing the most inferior version of a game they've been looking forward to all year?
Of course the sony reputation and trust built over several generations is hugely important too but I think general public are also driven by playing the newest games on the newest platform.
