I had my first S3&K run submission rejected because I didn't record the game audio. (I don't stream, and tend to listen to Spotify or podcasts through my PC while playing emulated games. From some brief googling, apparently it is possible to use Virtual Audio Cables to get OBS to record only specific applications rather than all Desktop Audio, but I haven't looked into setting it up yet.)

The run rejection comment from @BenInSweden said that the S3&K rules have now been updated to read: "Game audio is required and must be at an audible level throughout the run."

Although I would have preferred to have known this was a requirement before I submitted it, I'm not objecting to this rule change (I appreciate that audio can be a way of identifying spliced runs) or to my run's rejection (it wasn't exactly a great time)!

Two questions:

1. Now this this rule update has been applied to S3&K, will the rules for any other classic Sonic games be updated to have the same audio recording requirement?

2. If so, should other Sonic forums get threads formally announcing this rule change, to notify anyone else who might miss it?

Regarding your post me and other mods will be updating the rules when we can to reflect this. If there are any changes made to a game, it's always announced in the Sonic Speedrunning Community discord in it's respective channel. In the past I have made announcements on the forums, but from past experience not a lot of people check them. So it might be best to join the discord to keep an eye out for these announcements. I'll continue to make the posts on game changes in the forums just to be safe though.
