How would I go about creating a multiple Sonic games page? I can provide a video link and description but as far as the link to an external page I'm lost. Can someone advise me for that?

This has already been discussed in the community Discord and the consensus was that there is insufficient interest to warrant making something like this.

There's little point in creating a leaderboard for one or two people who want to try something like this.

as drakodan said here. however, please do not let that stop you from running multiple sonic games back to back. its really alot of fun.
