Maybe. But given that, why do we need a split at all? Why not just lump everyone in the same universe (better) and the choice to PvP or not is down to individual player encounters?
Sure. But the choice is only down to the player pointing the laser. The player being targeted has no say in the matter.
Similarly, the standard PvP-consensual only gives the choice to the player being targeted. The player pointing the laser can only shoot if the other player allows it.
Thing is - we are all going to be flying space ships with big enormous guns on the front, in a massive universe, rich in detail. It is (or will be) life sim in 3300. Sometimes you will get shot at, sometimes you shoot back. I fail to see the point of a PvE mode when there are already two single player modes available where you have no chance of meeting any other player (and hence can't get blown up by another player) if you hate PvP that much. There are other types of PvP besides combat after all.
People want to meet other players and don't ever want to shoot or be shot by them.
Let's say for instance I'm out exploring - effectively doing PvE, the kind of thing the PvE-only guys want - and find a nice ore belt somewhere out in an unexplored area. "Great!" thinks I, I'll just mine a few resources, take it back to civilisation along with the location to sell.
Then at that point, an unknown ship appears on my scanners and approaches... he's seen my heat signature & traced it to where I am.
What do I do? Do I protect my "investment" in finding the belt first, by blowing him up, do I risk him taking the ore I've found & bringing his friends along to strip it bare? Or maybe I make friends & share the findings.
In a PvE only mode, there is only one option. One single choice of what to do. In PvP there are several possibilities and the whole gameplay is richer.
Having the choice of a PvE or PvP option removes choices from the game - it doesn't increase them. At all.
False.
If, at any point, you want to shoot a player, or be shot by a player, you choose PvP. Then, when that scenario arises, you have the several possibilities open to you.
To players who don't want PvP, every single one of those options except one is entirely unpalatable. One of them isn't even your choice anyway! To a PvE player, there was only ever one choice all along. The others aren't options to someone who dislikes PvP.
Again, going back to the "vegetarian" analogy; asking customers at a restaurant to tick "Vegetarian: [ ] Yes [ ] No" doesn't reduce their choice, but it does improve their eating experience. Instead of ordering from the menu of "Steak, Bacon, Spam, or Fennel" and risking someone else buying them Spam, they just get Fennel, because that's what they would've ordered anyway.
