If it doesn’t have co-op, and that is an if (so far as I know), it won’t really affect my decision to buy.
I’ll genuinely be buying the VR set just for it as I never had a reason to prior to this. Also, for some reason I don’t know, VR gives me CRAZY motion sickness.
Would I enjoy co-op? Yeah, definitely. But it won’t be a dealbreaker for me, and it wouldn’t have edged me over the line to make the purchase either way. The snippets (like the slowing down of time) shown in the preview, proves that this game may offer functions not available in the original, and I’ll be seeing Pandora in a far more immersive light than I may have before.
Yeah, it would be neat for me to be able to do that with a friend, but while co-op would be a major aspect of my decision making in purchasing an FPS/RPG in the vain of BL2 (original), it really wouldn’t weigh heavily on the VR experience aspect of it. I want to be immersed.
Also, this could be a way to introduce a single player modeled BL to a portion of the population that may have avoided it as a game which benefited heavily from being played as a multiplayer experience.
