I hope PVP will consist of corporations hiring players to do jobs, so you'll have teams working against each other to steal/protect some manufacture or things like that. It would add variety and replay value (different teams would play differently)
If it's just deathmatch, after 6months you'll have the "best gear" tutorial on youtube and everyone will play the same build...
Same, Coop missions could be cool, but better if it could be randomly generated, etc...
Cause, Gta online, once you made all the mission, it's just the same thing again and again...
Don't let players bully each other also (Gta was plagued by it). Unless it's an assassination objective.
There's plenty MP thing you could do using the world around, just avoid the casual pvE or pvp that everygames have (shootings hordes of mob without goal or just turning into a deathmatch).
Cyberpunk won't be the best driving game or shooting game, so people won't get it to play a competitive deathmatch or shooter etc...
Now, putting those on the side (small underground races or small deathmatch) but the main goal being deep edgerunners team working against each other would make it way more interestint to spend time online.
I've play a few time GTA online, had fun for a few hours, then saw that people playing it for 6month before me used to bully me and kill me over and over, I just gave up and never played it after.
Was boring.
