There’s plenty of free titles that will have you covered.
Getting a 3rd camera is more important that buying a few games imo, that way you will have 360 tracking which will improve the games your games and the experience you have with them, with the exception of SuperHot VR and Arktika.1, they are front facing titles.
I would say my must have games are:
•Onward
•Bullets and More (get whilst it £6)
•Pavlov (get whilst it’s £4. Not listed as Oculus supported but works perfectly well)
•SuperHot VR (far far to short, but it’s an incredible experience and worth the price tag imo)
•Lone Echo (I don’t have it as yet purely because I’m waiting until i have a graphics card to do it justice)
•Artika.1 (from the makers of the Metro series, teleport and front facing only but I loved it)
•Rick and Morty (if you like the TV show, buy through steam and play through the game, you will have it finished in under 2hours with plenty of time to spare, and refund it)
It’s an amazing time to get into VR, some great titles out there for everyone, I play more genres than ever before because playing them in VR only makes them better, also never again will I play another ‘pancake’ FPS, there Just boring in comparison.
If I was to recommend Just one game from my above list, I would say Bullets and More, it might not look as good as Pavlov or Onward, but for sheer content it can’t be beaten, plus it’s Battle Royal game mode is really REALLY fun!
Pavlov does have a very active map modding scene on the steam workshop too
