Really no such thing as "combos" in PnP CP of course. Not to say they couldn't add some but I can't see any reason to as that's just Action Game or PvP "flash" that only exists to give players some buttons to push so they can do Hollywood/James Bond/Bruce Lee style "fancy moves" no one has ever seen or used in real life.
Pick your target, squeeze the trigger, hope your round(s) hits. That's really all there is to it.
Maybe a bit boring as a game but PLENTY exciting RL!
I said that in the way of "something more exciting than mashing a button to punch for 3hours straights".
There will be time when you'll have to use your punch (no more bullets, or being in a place where you can't fire at all, like filled with explosives or in a plane, etc...), and as much as gunfight, "hand to hand" fighting will have to be somewhat nice to handle, You're right when you say that no one use "combos" in RL, but at the same time, no one just do the same punch over and over lol, I doesn't need a whole mechanics around, just a few special to throw your enemies, disarm them, or put them on the ground, a kick button, a punch, and that's it, with a few combos that you could learn as your skill goes up, wich would be helpfull to pressure your enemies, not a "combo" like in a fighting game, but being able to throw more than "1punch at a time" as your skills goes up
Just make it "fun" to fist-fight, there is no way all the combat system would go in gun-fight and nothing for the hand-to-hand or the melee weapon.
The same for the melee weapon, someone with 1 in sword skill should just hack and slash, but once you're a Pro (10), I'd think you should be able to do cool stuff with your sword
(mostly if Monoblades are there, who never wanted to play a cyber-ninja? lol), just look at a bruce lee or Jet Li movie, look at how they move fast, etc... that's the kind of stuff i'm talking about, not turning it into a beat em all, but to have a feeling that "I'm doing martial art" more than something like GTA where you have to mash your button to fight (in fact, it shoud look like this when you have no skill in fist-fight)
But, If i've no more bullets and a few kung-fu skill, I'd be able, if not to kill, at least to kick the ass of a guy with a high level.
Combos weren't in the pnp, IMO mostly because you don't "really" see what you're doing, just as for the cyberspace, having some martial art needs to give you some ability, like throws if you do catch, cisors kicks if you do tae-kwon-doe, quick punch, etc... If you do karate, etc... just having a wide variety of style, with each on his own "capacity", that's how it was handled in the pnp after all, CDPR just need to refresh this, because there is no way you can't do better stuff as your martial art skill grows up, IMO choosing what kind of martial art you want to do should be as much important than choosing what kind of gun you want or what kind of hardware you'd like to use.
