Oculus Go and Vive Focus doesn’t have fully tracked controller, so you will not be able to swing your sword or use your bow and arrow.
Oculus Go even have no room tracking, so you can use it just like a Samsung Gear VR with a phone, but much cheaper, because you don’t need a separate phone. I have read, the performance will be “significantly better” than a Samsung Galaxy S7.
Santa Cruz will have room tracking and tracked controller. So technically you can play with this Orbus. But there are no infos (as far as I know), what kind of games you can play. Maybe it’s using Oculus Store, and all the developers just can add the routines for Santa Cruz in their games, to compile it for this hardware.
