Cross buy games are games you buy on Meta store and get the PC version for Free, most games have cross buy, but there are many that do not, the Cross buy filter on meta store does not list many of them. There isn't a definitive list, so I add them as I find out, ill also add a list of ones that are not Cross buy
Not Cross Buy or does not have a PC version
Beat Saber (although DLC is supposedly Cross buy)
Superhot VR
