You may not realise that we are currently in the midst of a VR Mod rennaisance:
Have you seen G-Rebels? Gunman-Contracts? NMS. Games such as Doom 2016, Assassin's Creed Odyssey, Half Life 2, many many more are being modded currently.
I'd also recommend games such as Pistol Whip and Synth Riders if you'd like to exercise at home.
There are now many good quality games, and I purchased a headset only a month ago.
