How Sonic the Hedgehog was conceived to help Sega compete against Nintendo in the early 90s was discussed during a postmortem for the original game at this year's Game Developer Conference.
Sonic superfans The Great Lange and Murasaki Fox have whipped up a prototype for a fan-made game called Sonic Utopia and it's got a heck of a trailer.
I love looking at deleted scenes from films, especially ones that tell a story we didn't get to experience in the final cinematic release. For example, there are the deleted scenes from The Empire Strikes Back in which the wooly Wompa runs amok in the Rebel base on Hoth.
Sonic the Hedgehog's longtime nemesis Ivo "Dr. Eggman" Robotnik has commandeered the already bizarre Twitter account for the Sega mascot.

The Hidden Palace Zone was intended to be a bonus level for players after Sonic had collected all of the game's Chaos Emeralds. But the map was cut during development and left to lie half-finished within the game's code.

Nintendo plans to add brilliant Square Enix Super Nintendo action role-player Secret of Mana to the Wii Virtual Console on Boxing Day.
Has it really been 15 years since Sonic the Hedgehog 2 first hit screens? Yes, buy a calendar. Then look how far games have come. 3D graphics! Free-roaming environments! Intense online multiplayer battles for up to 32 racists at a time!
All very well but sometimes you want to be reminded of how good games used to be. When they were good, obviously, not when they were Top Gun movie tie-ins or had the word "Gex" in the title. The new Xbox Live Arcade version of Sonic the Hedgehog 2 shines as a candidate for the job.
Primarily because SEGA has been sensible enough to Leave Things Alone. All the original levels are present and correct. They are as expansive and exciting as ever. The sheer speed of the game still has the power to thrill as you send Sonic zooming, spinning and bouncing in all directions.
Classic 16-bit platformer Sonic the Hedgehog 2 is this week's Xbox Live Arcade release, and will go for 400 Microsoft points (GBP 3.40 / EUR 4.65) when it launches around 10am BST tomorrow.
