3. Sonic 2XL Mod Transforms Gold Rings Into Onion Rings, Make Sonic Fat
Have you ever tried to play through a Sonic game while deliberately avoiding the rings? Yeah, it's a pretty stupid thing to do, given that having no rings provides you with no buffer when injury occurs, and you'll just die straight away, but a hilarious mod for Sonic 2 (called Sonic 2XL) puts this notion into ridiculous practice. The lovely golden rings are now delicious, fatty onion rings, and every time Sonic grabs one, he gets a little bit fatter, slowly turning into the butterball you can envisage above. Take it too far and Sonic even dies from heart failure, so the player has to ensure that Sonic runs around a lot to burn off all the fat. Oh, and to make this mode even more challenging, if Tails comes along for the ride and starts picking up onion rings, you'll be the one taking the calorie hit for it for some reason. For those who've breezed through Sonic countless times, it's nothing if not a brilliantly alternative way to play one of the all-time greats.
