The Oculus App Lab game list has dozens, maybe hundreds of games. A lot of them are free to play. A lot of them can be played by a single person. It doesn't necessarily need other people to play. It will allow you to get used to the controls and stuff like that if you're new. I mean the limit is only the space that you have on your headset. And also keep in mind if you download a game and then delete it, it still will remember that you used it so you can always do that and delete stuff that you don't use a lot and re-add them later. I would recommend using the filters to find stuff that is in your interest group because if you scroll you'll just be scrolling forever. But you know, a lot of free games. Try it out.
