just got my oculus rift cv1 up and running (bought second hand, had to go through oculus support and bought a refurb headset, probably going to sell the old headset for parts)

I'm in the process of setting up my room, What's a good first VR game to get? Should I dive in and just get alyx, or are there other (cheaper) games that can give me some good training and plenty of time in VR.
