Half-Life: Alyx has been out for two days and so far, it is quite the success. The user reviews average is now labeled as 'Overwhelmingly Positive' with 97% approval and according to SteamDatabase, the game peaked yesterday at almost 43K concurrent players, which is a record for a Virtual Reality only game.

Will the game remain a VR-only title, though? In an official capacity, that is likely. However, given the moddability of the Source 2 engine, many expect a non-VR mod to appear relatively soon.
