The Genesis framework's second title, and the de-hardcoding work that made a second game possible at all.
Two months after the Sonic the Hedgehog tech demo, the Genesis ecosystem gains its second playable title. This post announces Sonic the Hedgehog 2 running natively, and is frank that at this stage the milestone is playability rather than polish.
The engineering story is about what a second game forces on a young framework. The original bring-up had let Sonic 1 assumptions leak into shared code, and supporting Sonic 2 meant de-hardcoding that behavior so the runner served both games from common machinery. That cleanup is the less glamorous half of the ecosystem model: the first title proves the concept, the second proves the framework.
The post points ahead to Sonic 3 & Knuckles as the next target, keeping the roadmap inside the same family, where the games' shared engine lineage lets each title build on the previous one's fixes.
