Last month’s news that SEGA and Baldur's Gate/Neverwinter Nights/Jade Empire developer BioWare were joining forces to create a Sonic the Hedgehog RPG for the Nintendo DS came straight out of Bizarro World. Now, BioWare chief Ray Muzyka has shed a little more light on a project that has taken everybody by surprise.

As well as promising that some of the world’s best writing and designing talent was working on Sonic, Muzyka also discussed how the studio intends to translate what is traditionally a fast-paced platform game into a rich, story-based RPG.
