It's only the hundredth-and-something entry in the franchise in the last 17 years. (Wikipedia's list of Sonic titles runs a whopping seven pages! I had to get special permission from our IT department to print it out.) So if it's seemed to you that SEGA's most recognizable character is getting a bit long in the tooth, well, you don't know how right you actually are."
