I've never played Chu-chu rockets before, but all the same it's nice seeing it make this comeback. Heroes feels like a new place for Sega to make low-key announcements on upcoming projects.
Yeah, sometimes I wonder why they decided to release this set of heroes?
It has to tied to something, and that probably their other projects.
Shenmue?
Shenmue 3 released (eventhough turned out it's delayed).
Altered Beast?
Launching of Sega Genesis/Megadrive Mini.
Chuchu Rocket?
Chuchu Rocket Universe released for Apple Arcade.
