The Oculus Quest 2 is curse and blessing. Pick up and play, sell your soul to Zuckerburg!
I have found the headset is not comfortable and this seems to be a common theme amongst reviewers. The display is not super clear and the way you wear the headset can ruin the sharpness of the visuals when moved 1mm.
But, the PRICE! It is so cheap and if you are willing to hunt around there is a lot of high quality free content.
There is a set of hidden games on the Oculus store that are pre-approval. Not necessarily free, but, most are. To get to them open the Oculus Browser in the headset and search for the web address
https://applab.games/
Then any game listed can be installed directly by following the link and making sure you are logged in. I had to allow Oculus permission to connect to Facebook.
One of the Games I tried was "Puzzling Places Beta" which is just a 3D jigsaw puzzle experience. But, it is so good. Really well done and very relaxing. Also, get very hard. From 20 pieces to 100 and then 200.
