Sonic Origins was conceived alongside Sonic Colors: Ultimate (2021) following the release of the 2020 Sonic film. Because the film brought many new fans, Sonic Team head Takashi Iizuka wanted to make older Sonic games available on modern formats.[8] Iizuka noted that though they are frequently rereleased via emulation, they felt "retro" on modern displays due to their 4:3 aspect ratios; he wanted Origins to modernize them with widescreen support and new features to appeal to both new and longtime fans.[9] Sonic Mania encouraged Sonic Team that there was still an audience for 2D Sonic games and the series' 30th anniversary provided the "perfect" opportunity to develop a compilation.[3]
