Depending on who you are, you may feel that SEGA has set a low bar for Sonic games. Whether or not that may be true, at the very least you can find comfort in knowing that SEGA has at least some sort of bar.
Recently a user on Youtube started uploading footage from a title called Sonic Extreme, not to be confused with the similarly canceled Sonic Xtreme. The footage shows that the title is a Sonic skateboarding title, possibly the precursor for the Sonic Riders series. The title was claimed to be found in a development system for the original Xbox.
There’s no real credentials here, so it could very well be fake. Either way, it looks really bad. Sure the game is in an unfinished state, but this build doesn’t give the impression it would have been anywhere near a decent title.
You can check out all the footage below.
