Sonic Team head, Takashi Iizuka, has reiterated in a recent interview that he really wants to make a new entry in the Sonic Adventure franchise, ideally Sonic Adventure 3. However, Mr. Iizuka said that creating a fresh new Sonic Adventure game in 2023 would require a massive budget from SEGA due to its scale. It would need much more investment to make than it would have back in the days of the Dreamcast. Still, Sonic Adventure 3 would be Iizuka’s choice for the next Sonic game after development of Sonic Frontiers ends.
“Instead of a feature, I would like to use these golden keys to kind of make the next Sonic Adventure game. I was there for [Sonic Adventure] and was there for [Sonic Adventure 2,] those are my games. I really want to continue creating the Adventure series.”
“When you look at all the games that are out there now and knowing the kind of expectations for the next Sonic Adventure game would be, it would take a whole of investment from the company, a lot of development time, and a lot of game volume to really bring something to market. But that is what I would use the golden keys for.”
