When using the Oculus Quest 2 headset you are required to link the Facebook account, and if your Facebook account is not in good standing, you will not be able to use Quest 2 at all. Because of this connection, you will have to keep that account to have access to the purchases you have made. You don’t necessarily have to link a Facebook account yet on older Oculus devices, including earlier quests, but as UploadVR pointed out, support for individual Oculus accounts ends in 2023 and then All Users will need Facebook.
If you deactivate your Facebook account instead of permanently deleting it, you will not be able to access any of your Oculus information. However, this can be reversed by reactivating, while the removal method does not have “undo”. If you create a new account, you will have to repurchase all of that content.
Despite these restrictions, Facebook has recently made its Quest platform quite enticing. The latest iteration is less expensive, lighter, and includes a higher-resolution screen than its predecessor, with a more comfortable strap design. Not having more versions of the Oculus Rift, the company is on an all-in standalone headset, which can also play PC-powered VR games via the Oculus Link cable. This includes high-end VR games like Half-Life: Alex, essentially meaning that you’ll only need a VR headset unless you’re interested in playing the PlayStation VR exclusive.
It is also partnering with other game companies to bring new blockbuster games to the platform, including Medal of Honor: Beyond Abv and Entertainment and new Assassin’s Creed and Split Cell games from Ubisoft. Otherwise there has not been any split cell cell since 2013.
