I think it depends strongly on your taste for getting into a series (do you want to play the best game first, or work up to it? Etc) However, if you enjoyed the Murder of Sonic the Hedgehog you probably want to look into the IDW Sonic comics, which are being adapted for mobile formats on webtoons for free right now once a week.

Mind you, thats the IDW comics, not the old archie ones, which… Have a certain appeal but are so unhinged.
