>>138913880Sonic and Cream literally do have more interaction. Way more interaction. They interact loads in X, heck Cream's very first episode is Sonic saving her, and Sonic giving her flowers and comforting Cream when she's missing her Mom in episode 7. She cheers for Sonic in the battle arc. In the comics Sonic plays teaparties with Cream because she wanted Sonic (and ONLY Sonic) to be with her. Cream and Sonic have an entire Sonic Channel short story about Cream wanting to come along with Sonic to fight robots and how much she loves and admires Sonic. Cream spends all of Rush waxing to Blaze how amazing and inspirational Sonic is and how he's her hero and the bestest most amazing person on earth. Cream's latest new Sonic Channel profile describes her as being Sonic's cute Imouto, nothing about Amy or Tails. Cream's first ever appearance is Sonic saving her from Eggman and Cream falling in love with him afterwards wanting to go everywhere with him.
In comparison Tails and Cream never interact at all. They barely even speak. He's just "some guy who hangs out with Mr Sonic". They have no chemistry and no interaction, canonically.
>>138913329They wouldn't, because after 30+ years they still don't interact at all since that's how their canon characters are: nothing in common. Tails literally has more of a relationship with oneoffs like Marine than he has ever even spoken to Cream because their characters are meant to have no relation to each other.
