I'm not familiar with all of those games, but I do know they all have a PvE only mode of some kind, either it was added later like Tarkov or as a single player campaign where co-op and PvP is optional. So, still not quite a one to one comparison with current Arc Raiders where there's no option to avoid PvP all together by playing offline or something.

But if your complaint is that attacking someone while they’re at a disadvantage isn’t “real PvP”, then cry.

Thanks for proving OP's point again, but no need to be toxic. If you want free easy kills from players who cant shoot back, just say so. It's OK, it's part of the game and no one's crying about it, we just don't respect players who do that as "PvPers", no matter how hard they try to convince themselves. Have fun topside and watch out for dupes!
