Can't speak for anyone else but Rockstar's games bore me out of my mind. They're a chore to play, the stories aren't emotionally engaging, the characters are unrelatable assholes and the combat is just dull. Last Rockstar game I liked was San Andreas and I think that's mostly nostalgia, if I went back to it today I'd probably hate it too.
And the gigs in this game aren't boring and has even less emotional engagement then any GTA game or any other open world game even.
The only character I felt some relation to is killed of in the "INTRO" of the game.
The fixers are so bland and has zero personality except for old asian woman.
I said it before for this game to become alive and engaging they need to add the small things that is missing all over the place that would have made this game great.
Best example I know of is Mass Effect 2 if you import ME 1 save.
With all the billboards and news cast, why is there not constant news after the heist and people in the street talking about what happened.
Also the short small things that exists in Fallout, ME series, Skyrim a couple or brothers or whatever arguing over something and you help them solve the issue by talking and later maybe there is conversation somewhere that someone helped them fix it.
Consequences where "YOUR" actions have obvious and serious impact one the game/world like killing off crew in ME or not getting crew.
Also as someone previously said why 99% of doors are locked, instead of more like Fallout almost all doors open but some places just has some containers and maybe a terminal with info.
Come to think of it for the modern technical game this is supposed to be where is hack able terminals to get info like FO games but it could have been made better and more modern computer hacking instead of just some arbitrary remote hacking and shards that are just boring modern file and folder.
In short what this game is lacking to be immersive:
Characters to relate to: Characters to do jobs with like the heist but more of them and you can choose who you want to go with.
Consequences: There is no real consequences of your actions, no matter what you do you end up in same place there is no way to save jackie. Saving Takemura dosen't really count since it is so hidden and doesn't really do much.
Small things: Random conversations, News reports of your actions ( Like if you eliminate all of the old cowboy gang, saving news reporter, heist and so on.
More stores, More clothes to wear, be different and let us upgrade anything to legendary so we can wear whatever we want and yeah lower the upgrading costs because they get stupid high very quickly and as immersion goes breaks it completely having to wait to pickup until your high level enough to make the item usable.
Upgrading iconic weapon should make it our current level and not downgrade it to the level when we picked it up, such a stupid mechanic and people talking about immersion that is very much breaking it yet again.
