Sonic the Hedgehog will be 34 years old this year, and just in case you wanted to brush up on the complex lore of the series, Sega has released a complete official timeline, stretching from "tens of thousands of years ago" up to 200 years in the future.
Right now, this timeline only appears to be visible on the Japanese Sonic Channel site, so it has to be machine-translated to view it in English, but it's seriously detailed. For each chunk of lore, the most relevant games are listed, so anyone who wants to attempt a chronological play order can do so, although some games appear multiple times at wildly different points in the timeline because of how they tie into various events, so don't expect this to work entirely smoothly.
