Updated August 1, 2023, by David Heath: Sonic Origins Plus came out back on June 23, 2023, and improved upon the original collection with a few features that probably should have been there to begin with, like Knuckles being playable in Sonic CD, and Amy Rose being playable in every game. Here are some of the best Sonic fan games that can be found on the net. In some cases, they may have helped their collaborators get work at the Blue Blur’s company. For example, there have been a range of Sonic the Hedgehog fan games and ROM hack competitions that have run for years, even decades, without Sega calling foul on them thus far.
Not every company is happy to see their IPs fiddled with like this, yet some tacitly tolerate it.
