Since we're talking about Sonic and how bad he's become, I came across this video today. This guy is a game developer proposing how he'd change the Sonic franchise to make it better.

He argues that Sonic needs to be retooled for an adult demographic. Make games that cater to the original fanbase, without pandering to them or insulting their intelligence.
-Get rid of his dated 90s 'tude and make him more relatable and unsure of himself. Sort like what they did with Laura Croft in the Tomb Raider reboot.
-Keep the speed but give him a more diverse move set for free flowing, fast action.
-2D hand drawn art style like the new Rayman games
-New mechanic that allows Sonic to use his items and environment. Which allows the player to approach the game in different ways, and gives it a deeper puzzle aspect.
He makes a good case for it. Too bad none of these ideas will see the light of day.
As a side note, it annoys me that some people pronounce it Sea-Ga and not Say-Ga.
