A couple of friends have Quest 2s since I showed mine to them.
Got golf to play together. See that Pistol Whip is on sale on Steam. If I bought the Steam version (for Linked/Airplay) could I play with native Quest 2 users. Am assuming graphics better for a decent PC too?
Are you talking about Pistol Whip, 'cause that's single player only.
Walkabout Mini Golf is cross-play between all platforms - Quest, Native Rift, and Steam VR (And mobile phone soon as well). Graphically there's no real difference between the versions, and doesn't need to be. It's not intended to have amazing graphics, just fun, challenging social play.
