>Replace the Chaos Emeralds with the Time Stones. The Chaos Emeralds were mainly used to travel through time, so it would make more sense for the Time Stones to be used. Shadow used it for Chaos Control once, but it's not important to the plot, so it can be cut out. They were also used to bring back Sonic, but Time Stones would still make more sense here. It's simple, the Time Stones, when used all together, revert Sonic's body back to an uninjured and alive state. Though, no kiss for this. Also, it would not be Elise that brings him back, but someone else, probably Silver. Also, that means Silver uses the Time Stones to become Chrono Silver (Like Super Silver, but Chrono).

>Make it so Iblis is indeed released when Elise dies, but not when she cries. But, she'll have a special sort of invisible energy shield around her making her impervious to attack. The shield is generated by Iblis' flames inside her. Now, when she's under severe emotional stress, she cries, which cause this shield to sort-of short out. Thus, it makes sense that Mephilis would need to kill Sonic in order to get Elise vulnerable, so he can kill her and take in the flames himself. He doesn't do it when she's very young, as Iblis was still weak, and it took time for it to develop enough for Mephilis. Though, if Elise were to die peacefully, the flames would simply fade away. However, a violent death releases them.

>Get rid of the Sonic/Elise romance. Because ew. Really, they just need to be good friends, that's all. I guess it's okay if Elise gets the hots for Sonic, but for the love of Solaris, not the other way around!

>Fix Blaze's placement in this. Even though Blaze's backstory has nothing to do with Sonic 06, that can be fixed. Have it so that the creation of Solaris by Mephilis actually affects Blaze's universe, too. This would have Blaze go to Sonic's universe, but because of time disruption, she ends up 200 years into the future, where she works with Silver to find out what destroyed their worlds. At first, they think it's Iblis, but they meet up with Mephilis. Silver quickly trusts him, but Blaze is dubious. Though, she goes along with it at first. Mephilis sends them back to kill Sonic (But not mentioning him by name), but Silver and Blaze get seperated. Blaze realises that "blue hedgehog" is refering to Sonic, so she goes to find him. Anyways, Silver will fight Sonic, but Amy will stop him from killing Sonic. Amy convinces Silver that Sonic actually is a good person, so Silver begins to doubt Mephilis. Silver meets up with Blaze, and Blaze convinces Silver that Mephilis is tricking them. Mephilis shows up to get them to go after Sonic, but Silver doesn't trust him anymore, so Mephilis leaves/dissapears. Silver figured he'd be going after Sonic, so he goes to Radical Train to head him off. He finds Shadow, mistakes him for Mephilis, and the two fight. Silver finds out that Shadow knows what Mephilis really is, so they go into the past to see. Anyways, Silver gets back to the present, meets up with Blaze (who found out that Sonic was going to Kingdom Valley), so the two go there to help him. They see the ship go down and explode, and they help Sonic go into the past to save Elise, though they go back to the future to take out Iblis. Blaze, being of royal blood (she is a princess in her universe), can take Iblis inside herself, and go back to her own universe to destroy it with the Sol Emeralds. Silver is sad that she leaves, but yeah. Blaze's universe is still destroyed even when Blaze destroys Iblis once and for all, however. When Solaris is unleashed in Sonic's verse, Blaze is yanked in. She helps out by going out and finding the Chaos Emeralds while everyone else find the Time Stones, and joins in the fight against Solaris with the Sol Emeralds, as Burning Blaze. She'd control similar to Super Sonic.

>Make it so Elise isn't captured so much. Captured at begining, rescued at Dusty Desert, she and Sonic bond a bit, then Elise gets captured again, and only saved at the end. Also, Eggman should only explain his plan once!

>Enemies shouldn't have health bars.

>Invincibility graphics should load for everyone.

>Have Power Sneakers in more levels.

>Have the Shield and Thunder Shield (The shield of the Yellow Gem, but with a larger area of effect)

>Get rid of all of the side missions, as well as the shop. Have power-ups be found in the HUBs and the levels.

>When you're hit, the rings have physics, like the rings from boxes (for consistancy)

>Levels should have more routes through them (not to the extent of Silver and Rouge's Tropical Jungle, though)

>Make the Forest Hub smaller.

>Add in a few level-specific power ups (Flame Shield that protects against lava in Flame Core, Wave Shield that allows you to walk on water in Tropical Jungle, and Heat Shield that protects you from the sand in Dusty Desert). These will reward those who are good at not getting hit.

>Improved lip-syncing.

>Flame Core shouldn't have the meteors.

>A glowing spot when an Iblis Worm is about to pop out of the ground.

>Get rid of the first phase of the Egg Wyvern, so you don't have to guide it into debris.

>Get rid of those enemies with the little laser/bullet sattelite things around it. Those are just annoying.

>In the Iblis larva boss fight, he should make all stalagtites fall at once to stop it from being so slow.

>Add in Chao Garden, with powerups for Chao being collected automatically when you defeat a foe (Chaos Drives for robots, Iblis Cores for Iblis monsters, and Dark Cores for Mephilis monsters). You go to a Chao, choose which to feed it, and how many. Other than that, similar system to SA2.

>Get rid of the second Wave Ocean in Sonic's story, and have Tails play through Dusty Desert.

>Have a mode where you can play any level with any character, excluding End of the World.

>Have multiplayer have all characters to use.

>For speeds of the characers, Omega's current speed will be "fast" speed, while Sonic's current speed is "normal".

>The rail grinding system of Shadow.

>Except for Omega, Silver, and Amy, everyone can damage enemies by jumping into them.

>Sonic the Hedgehog
-Sonic moves at "fast" speed.
-Mach Speed sections have less sensitive controls.
-Can change direction in mid-air during Mach Speed, and can also use homing attack.
-Spindash doesn't have a distance or time limit, but you can jump whenever you want.
-Remove the now redundant slide-kick.
-Remove the White gem, Yellow gem, and Sky gem.
-Add in Rainbow Gem (Super Sonic)
-Gems actually use power.
-Boosting into walls, either through dash pads or Blue Gem, doesn't stun you.
-Homing attack should be more rapid to use, with actual animations for bouncing off like in SA2.
-No Elise/Sonic gameplay.
-Lightspeed Dash gets its own button, and he has it from the start.

>Miles "Tails" Prower
-Moves at "Normal" speed.
-Uses tails to attack like in SA1.
-Flight works like in SA1, and has a meter.

>Knuckles the Echidna
-Moves at "Normal" speed.
-Punches have a bit more range to make them more reliable.
-Gliding doesn't loose height so quickly.

-Remove the kicking combo stuff from the homing attack.
-Homing attack is more rapid, like Sonic's.

-Her charge-up fire-tornado attack has meter.

>Amy Rose
