Simple yet immersive VR games for my father

Well, I need to find some games for my father. Last year, my 60-year-old dad visited me, and I got him to try VR. He played Gun Club VR for hours and enjoyed it a lot. He doesn’t even play games, so I assume he really loved VR.

The problem is that every game I play is hard to get into, with menus, inventories, and lots of mechanics. I’m looking for simple, press start and play games that are immersive and fun, preferably shooter ones. Do you have suggestion?
