I would turn the issue into a question of making it better than Bethesda (which shouldn't be hard) in what way? As a better shooter, or as a better RPG? Because Bethesda's aim is always at the dead center where combat is shit from a shooter perspective, and combat is also shit from an RPG perspective.
- Bullets lack 'impact', which is to say that there aren't enough animations in place for being hit by bullets. This I suspect will improve when launch approaches. (assuming they don't run out of time) CDPR priorities are elsewhere currently. On the other hand, it depends who you are shooting. There are prolly plenty armored cyborgs in the mix.
- Gunplay is 'boring'. Well, FPS shooter mechanics haven't really evolved nor CAN they evolve. I am only half-joking when I said I played the original wolfenstein back in the 80s and that I was already bored at FPS shooters when Doom 1 rolled around (The only thing doom actually added was map elevation). The gameplay is ultimately always the same. You have to go to pretty fine details, the nitty gritty, if you want to produce an impressive shooter these days. The market is unbelievably saturated. And I am 100% sure CDPR still wants this game to be RPG first and foremost so their priorities lie elsewhere. There's only so much you can achieve in this field with a half-assed job.
