Perhaps doesn't count, but Tails Workshop is mentioned in Sonic Runners. While Mystic Ruins itself wasn't mentrioned, it shows the original workshop from Sonic Adventure.

True like Sonic Battle I question the games canon to the main series, but Sega are pretty dedicated to this game to update it monthly.
