I voted for PvP, but I don't view PvP in the same way most other people seem to.
Its interesting reading this thread, where people clearly view PVP as the type of environment which finds itself in games such as CoD, MoH, Battlefield and other games of that nature. The name, player vs player, seems to define an arena style, 'pick up and play' atmosphere.
That being the case, I agree with the general consensus that it would not suite the ethos of PnP Cyberpunk and would not fit into its world.
Having said that, I would whole heartedly support a MMORPG, correctly done of course (I believe Eve Online has the best formula, and boasts the highest average player age of all, mid 30's).
Although I love deep single player story driven games (Witcher, Deus Ex 1 and 3, Mass effect series), I feel that Cyberpunk 2077 might miss out on a whole depth of game play which can only be experienced though a multiplayer environment.
In most MMORPG's we often hear the countless stories of children talking crap in the public channels, griefing and pointless killing. The stories you don't often hear are the creation and disbanding of groups, gangs, corporations and alliances and the history associated with them.
Think of what a MMORPG could offer;
1) Depth of involvement. Operations with people around the world, planning, scheming and ultimately actioning the same plots at the same time.
2) History. Everything you do will be remembered by someone, somewhere. That bar room scrap, that arse kicking in a side alley, that operation which felled a multi million dollar corporation. Years later people may still talk about that 'one off con' you pulled off.
3) Teamwork. No worth while task should be achievable by just one man, argumented or not. Dragging friends and gang mates into your op makes it more fun. And that is one of the biggest memories I had of the PnP version.
4) Game world depth. Eventually the game designers will not need to spend so much time a effort into NPC social dynamics. You would walk into a club and actual people will be in there, some pubs would be friendlier than others. Streets would have actual people walking down them, busy completing their own tasks.

I know the risks of MMORPG's, random killing, children talking bollocks and the possibility that some smart arse will con you out of all your money. But think of the benefits, playing with friends and maybe, just maybe, the chance to one day look down on other players from your penthouse suite.
