Well this is perhaps exciting, seems Valve are cooking up something new with a trademark application for NEON PRIME. The application notes it's for "categories of computer game software, electronic game software, video game software, computer game programs downloadable via the internet" and so quite likely some new game is on the way.
It could be a game but then again it could be anything and it doesn't mean something will be released, as we've seen in the past Valve (like a lot of developers / publishers) prototypes a lot and cancels plenty before they ever see the light of day.
NEON PRIME was sent in as a trademark application on October 10th, so by doing so it's become public and anyone can go in and see. It doesn't give us a lot to go on though mind you but sure would be exciting for a new Valve game (or series?).
Valve are certainly on a roll lately with Half-Life: Alyx, Steam Deck and Aperture Desk Job. They've said before that multiple games are in development, so perhaps we're finally getting closer to seeing one of them?
Then again, it could also be multiple years away and could even be a new VR game for their long-rumoured upcoming VR headset codenamed Deckard. Of which, we know that they're still working towards that too, thanks to a new job listing that clearly mentions the developer will be responsible for "prototype, ship, and support consumer gaming products leveraging visual-inertial tracking (HMD and controllers), camera passthrough, environment understanding, eye tracking, and hand tracking".
What do you think NEON PRIME from Valve could be?
Update 15/10/22: as pointed out in a comment (thanks) there's another trademark application for NEON PRIME that gives us a different idea of what it could be as it's "intended to cover the categories of entertainment services, namely, providing online video games; provision of on-line entertainment, namely, on-line computer games; providing on-line computer games and on-line video games; electronic games services provided by means of the Internet; providing information in the fields of computer games and entertainment via the Internet; organization of competitions relating to video games, video game education, and video game entertainment; providing information in the field of on-line computer games and on-line video games and computer games".
Certainly a little eye-opening. Is it more than just a game? A whole service? Perhaps finally Steam Cloud Gaming, their own streaming service? Or, a service attached to a game somehow.
