$80 million is still a huge money
When we look at that amount by itself, of course it is a lot but my point is that it is not even close to the budget of the other IPs you listed.
and imo, any game that is considered triple A game that looks it had a "budget" should be considered as a "blockbuster" game.
I don't know why you're putting the words budget & blockbuster in quotations but I personally wouldn't necessarily consider Ratchet & Clank a blockbuster game because by the very definition of the word, it's for an entertainment product that was a great commercial success.
Maybe I am wrong, but I don't remember any game in the Ratchet & Clank series to be on any bestsellers list for a PlayStation console, Rift Apart included. I don't see them on any list for best games in general for that matter.
And I disagree with your general idea that any game that looks like it had a budget should be considered a blockbuster game, because that's not what blockbuster means.
Anthem from Bioware was supposed to be their next big IP after Mass Effect, but failed to meet sales expectations. By your logic, since the game was AAA with a budget, it's a blockbuster. To me, the game is a flop. Basically the opposite of a blockbuster.
$200 million also isn't the norm, only few game's really get that budget
Literally every single IP you listed had at least $200 million in the budget.
Spider-Man 2: $300 million
gow Ragnarok: $200 million
Horizon Forbidden West: $212 million
Tlou2 just on Ps4: $220 million
So by all accounts, for Sony's blockbuster IPs $200 million
is the norm and if we considered R&C to be a blockbuster, then this IP is the odd one out.
and even Sony isn't having an easy time recouping their $200 million game budget, hence why we are getting these PC ports.
Ratchet & Clank Rift Apart also got a PC port despite having a budget that's a fraction of the size of the budgets for those other games. These ports also come several years after the launch of the game, so I'm sure it's more than just about recouping the budget.
