Why would they make PVE of any kind in MP when they have Single player for that ??? most of MP games are about PVP.
One reason would be because it fits with the whole PNP deal. I'm by no means a routine PNP player but my understanding is it tends to revolve around getting a group of people together and playing "together". This is not to say it would have to be co-op because, well, PNP has a lot of freedom in terms of what you can do with it.
I wouldn't say it's fair to claim most MP games are about PVP either. Plenty of MP games have a focus on players cooperating with each other. Others provide a wider spectrum.
If anything, I wouldn't be a huge fan of PVP for CP2077. At least, not using the formula you would find in, say, a competitive FPS. RPG's tend to have evolving characters, extended narratives, deep progression systems, etc. The game is clearly being built as a single-player RPG first and foremost. All of the mechanics and game systems are going to be focused toward that end. This approach doesn't tend to play well when you slap competitive PVP on top of it.
I'd prefer it if MP was built as small group co-op and/or setup in a way where players are arbitrarily dropped into the same game world, without any predefined goals.
My vote goes for Corp Wars, maybe even PVE style. You can do PVE missions against other players etc. Corp Wars is unique concept in game industry, only Cyberpunk can do it.

This I wouldn't have any issue with. Players "competing" against other each other though the environment. It could be quite interesting.
