I would prefer the roles remain in the game, or be present through some means in the setting.
Why?
Because they explore various parts of the setting differently, how people deal with the cyberpunk world.
I can always experience the same story of a Solo, Cop, or Netrunner in any other game, but a Media, or Rockerboy?
I would very much like for all the roles to be present, either as secondary Role options, or regardless as major NPC's.
However, the reality is, that trying to implement all the roles in a game as playable would require each Role to have their own varied and resource consuming series of mechanics and animations. Rockers above all, as they would also require original songs (which becomes a nightmare on resources especially if the characters are voiced... that's a song for each voice, and no one would be happy with a rocker with just one song.)
So if you try to do this with all the characters, you are going to end up with a really short, and disappointing game, because the resources are used up before the game even begins.
You could go the "crazy street poet/ranting instigator" route for Rockerboy, andthen he would only take up as much reasources as the other classes, which are still considerable... but then the name would confuse people, and I dont know how many people would want to play a Rocker who prime focus wasn't tied to his music.
Every time I try to picture a Rocker in a firefight, I always flash back to that Johnny Cash-themed assassin from the 2004 Punisher movie. I'd play the hell out of a character like that in a video game. Although in all fairness, he was really more of a Solo posing as a Rocker.
The best I can come up with for Rockers as a main character in the game would be something like Rock and Rule... but again that requires special concerts for the characters, special animations, special mechanics all around. And what if you don't want a guitar rocker, but want to be a drummer, or a sax player, or want to play the xylophone....
There are lots of examples of Rockers in Cyberpunk media... Priss and Vision in Bubblegum Crisis, but the reality was that they were both Solo's with musical talents. Ellen Aim from Streets of Fire, Faith from Strange Days, but they were supporting characters.
Now, its possible that the mechanics for rocker could be limited... they only sing/play instruments at recording studio, a night club, maybe a charity gig, radio interview... and then maybe a big concert at the end. But that stuff has to be tied to the game somehow, and the amount of resources the animations would consume could be staggering. As well as the budget concerns for the writing and recording original songs for the band to sing... unless its a cover band... but really, could you EVER actually respect a cover band.... some of them have a good gimmick, like Me First, Dick Cheese, and even UB40... but there is no point where a cover band is anything more than a gimmick at best, and more commonly just a bunch of sad ass posers who can't do their own thing. Even if you try to pass off non-original music as the bands songs, you have to have a library of male and female songs, in equal number... to be set aside exclusively as the in game bands.
In terms of resources and budget, Rocker boy is going to use exponentially more than all the other classes combined...
One of the flaws in CP2020 is that it lends itself to "80s action movies" a little too well. True, if Refs are hardcore about implementing things like limb damage criticals, stun/shock and heal times, the 80s feel goes bye bye very fast. But many GMs let those things slide because the players are having a shoot-em-up-good time.
Problem is, you then have a game that is mostly about shooting, stabbing and the gear that supports that. Pretty one-dimensional and a waste of a lovely, morally complex setting.
So I hope the non-combat Roles are emphasised, not reduced.
Cyberpunk 2020's Interlock system is rare in that it can be run straightforward as an incredibly realist (for a game) and dangerous combat experience, or it can be givn to awesome cinematics, both with ease, and with varying measures of each other. It's what I like to refer to a "cinematically realistic".
It's Jason Bourne, Raid: The Redemption, and John Woo's Beter Tomorrow II all rolled into one... it can be pedantically boring, or it can beover the top, but is best in the middle ground of cool without being silly, dangerous and brutal without being boring, fast paced and epic without being ridiculous.
I hope the non combat roles are emphasized as well. I truly do. Outside of Nomads and Solo's, Fixers are my favorite class. Even Nomad by itself is not a combat class, it's more of a dusty Fixer with survival skills and an affinity for vehicles. And Cops are my favorite campaign to run for, even if most of my players just really dislike them (as a whole, not just the game role).
This is why I still hold to the idea of a primary role, and a bunch of secondary roles.
But its already been beaten into my head that CDPR isn't capable of creating nine seperate stories, even with each episode only lasting 5 missions. So I am extremely baffled as to how people will think the entire game can revolve around the nine roles, without coming off as tritte or silly, or without telling 9 completely different stories from start to finish.
A lot of people seem to just be saying, I hope they can, or they should... or they are focusing on how to implement their one favored class... but no one yet has come up with a way to integrate them all, equally, for the duration of the game, and have it make any kind of sense within the story and with resource limitations.
