Sonic Racing: CrossWorlds is releasing soon on September 25th, and you'll be able to try it out again on September 17 with a new demo. Unlike their previous tests of their networking, this demo will be single-player only.
As a reminder when covered previously on GamingOnLinux, it is Steam Deck Verified - but it also requires an active internet connection at all times even when playing solo. It also uses Denuvo anti-tamper DRM. Confirmation of the demo comes from the official Sonic account on Bluesky.
Latest trailer is below:
