Sonic Team
1991-2022

Sonic Frontiers is a Wonderful Conclusion to the Sonic the Hedgehog Game Series. To see Earth & Mobius return to their own universes and the Cosmos going back in order is joy to behold along with a commitment to a Theme akin to Tales of Graces & Final Fantasy 6 where it went from a Blaze of Glory to a High Note Song of Victory...

"Once there was a child that discovered a lost seed.
He planted it in his yard and took care of it everyday.
Over time, the lost seed grew up & blossomed into a beautiful flower.
What do you think happened after that?
It turned into a bright shining star that watched over everyone!
This was its way of thanking the child that was so kind to it...
Which Star was it?
Well... its the one we all know best.
Our favorite star of all."
= Sophie (Tales of Grace Future)

Sonic, Tails, Knuckles, Amy all returned home to Mobius, the Cataclysm War that caused Mobius & Earth to split apart, even after 1,000 Years Later has ended, only this time for good.
So while this may seem like the end of Sonic the Hedgehog's Video Game Series, it could be the Start of Something More New & Different.
Only Time will tell... because I hope Tails builds a Time Machine to find out.

And with that, the Sonic the Hedgehog Game Series leaves the 4K HD Gaming Era."
