Been playing games since 1988 and I can tell how the gameplay feels from the slow-ass-paced gameplay they've released + all their games except RDR1 that felt much more agile and back then hoped that all their games would improve from then. Rockstar games feel like Fall Guys on steroids.
Ive been playing games since then too and Ive been testing games for awhile. Its meant to be a semi "realistic"
modern action game. It does what it does.
When you're not aiming, movement can feel a bit floaty and slow reaction but when you're aiming it controls just fine.
Not as floaty as fall guys either so its less on floaty steroids then fall guys, not more.
The 3rd person movement isnt as grounded feel like Gears or RE but its not horrible to control or feel.
Slow ass gameplay? Not sure what you're expecting in a semi realistic modern world shooter. Its not meant to be vanquish or Dmc. Or Cod etc. Its meant to be more realistic than a Saints Row.
Sure they could improve there melee to be more like TLOU2 but something like sleeping Dogs, as much as I like it wouldnt suit it.
They've invested into making the world and npc's deeper, more detailed, feel more alive. Like a open world sim. With plenty of activities and depth and attention to detail. Its what they are aiming for, not the most fast paced fun combat. There trying to make it more sim like than GTA5.
And if you can name me one game that comes close to it in that department, you'd be surprised its hard to find. Its what they are aiming to be the best at
Driving and combat is fine for what it is, could jt be better yes, is does function well and fell fine, also yes
Its never meant to be Uncharted or Vanquish, its not exactly bad before, maybe not up there with the best but not much wrong with it and its probably gotten better in GTA6.
If its not your thing thats fine, but from the combat so far it looks great. Is it slow paced missions and story, maybe but thats a you thing. Alot of people hated that direction in RDR2, I loved it and glad they are doubling down on it
