A strange little side quest
The fun part of looking behind Blobs and Sheep is seeing how many older ideas are still alive in modern play. Sonic the Hedgehog launched in 1991 and turned speed itself into a defining platform-game mechanic. The surprising part is how quickly the next milestone followed. Doom changed game design and distribution in 1993 by separating its engine from content and spreading widely through shareware. It is a good reminder that simple game mechanics can carry a surprising amount of history.
