First off. We want to congratulate Sonic Team for coming up new Open Zone gameplay  with Sonic Frontiers.  The game is graphic is  looking great and beautiful. However a lot of fans are kinda concerned on DLC. Sonic Origins had a questionable DLC and Deluxe edition.

DLC should consistent of extra skins, extra levels or Characters

 Deluxe edition should include music, concept art and behind the scene features and the DLC. 

We have some suggestions for DLC. 

Suggesting DLC Listing From Plausible to hard to Do. 

( things that are accessories ) 

sonic boom bandana and wrapping and shoes 

Chips bracelet 

Sonic Riders equipment 

Sonic and the Black knight - glove and armor. 

Sonic and the Secret ring - ring 

( Things that are skins )  

Smash bro ultimate sonic skins 

Things that are complete remodels 

Sonic adventure model 

Sonic adventure 2  model 
 
Sonic Boom Model 

Metal Sonic model 

Sonic 2006 model

Movie sonic model and ect, i have made examples of skins as you can see

if you want to go further with this i can also add skins to different super forms, such as super movie sonic, or super adventure sonic, or excalibur super sonic armor, and also have excalibur armor

as blue sonic too  as armor like the monster hunter armor

with a additional glove he has in the black knight game.
( Including other sega IPs ) 

For including other sega ips. 

Include phantasy star, Yakuza , Endless dungeon , etc

(Capcom IP since monster hunter was included ) 

Megaman skin and more

 

 

if this does  it get included then it would be a HUGE BIG missed opportunity and a HUGE disappointment to such a AMAZING game.

if you do add these then sonic in his new cool game sonic frontiers,  will get so much more popularity and diverse for the fans to enjoy

please sega, as a huge fan base that kept Sonic and his legacy alive after all these years, after all these ups and downs, it’s the least i could do, with frontiers.

if any of this. Would be included we would be happy. As a fan base that you included our feedback.
