If you're talking PVE experiences, on the FPS end Payday 2 is an amazing co-op VR experience, just be sure to download the VR fixes to make it more proper and immersive. The base game regularly goes on sale for 1 dollar and it has loads of DLC you can get for more content if you like it. Pavlov has the numerous Call of Duty zombie map mod ports and custom maps on the workshop, wave defense mode with 4-10 players where you have to defend against increasingly tough zombies with in map progression like gun and ability upgrades. It goes on sale for 10 bucks or less. SURV1V3 is also a criminally underrated game with up to 4 player co-op through an open world zombie infested place, has a long campaign to play through or a survival mode. Think of it kind of like diet Sanits and Sinners with co-op and slightly less intense crafting mechanics. It's almost never on a good sale for more than a couple bucks and stays solidly at 20-25 USD.

If you like Racing Games Assetto Corsa and Project Cars 2 usually go on sale for pretty cheap as well. AC in particular has a massive modding community and loads of custom tracks, but the UI navigation is pretty ass as you have to use the desktop somewhat. They can be cheap.

L4D2 has a pretty well working VR mod that support co-op, be sure to read the directions to not get VAC banned however, though it's missing a lot of little things which may or may not bother you, such as no manual reloading and UI's not really there. But almost everyone has L4D2 or it's a couple bucks on sale so may be worth a try, might help you decide if something like After the Fall, more built for VR, is worth it.
