Why are so many being irrational about this?
It's a mobile spin-off based on Ratchet & Clank. They're finally doing what Nintendo's been doing for almost 10 years: mobile spin-offs to help grow mindshare of IP, without devaluing their console by straight-up porting console games to mobile (and having their 1P studios spend time on said ports).
I mean, Nintendo's avoided SIE's mistake of porting their own console games to PC, so they've still been better at avoiding that devaluation than SIE IMHO. But that aside, this is a good move for expanding R&C's brand mindshare in the market. It also looks sorta like a GAAS, so that's killing two birds with one stone, without sticking one of SIE's 1P studios on such a thing (so no Bend or Bluepoint situation).
If this were a new IP on Switch 2 I bet a LOT of the same people clowning or hating on this would've been perfectly fine with the game or even hyped for it. The double standards are extremely real.
