Sonic Adventure & Sonic Heroes concept art shown for first time by Sega

The official Sonic the Hedgehog YouTube channel, which is over 1 million subscribers strong, conducted an Extra Life charity stream this weekend to raise money for Children’s Miracle Network. The stream had set up milestone donation incentives, including for never-before-seen Sega concept art for Sonic Adventure, Sonic Adventure 2, and Sonic Heroes — and all of those milestones were met. As a result, via Tails’ Channel, we have a plethora of brand new Sonic the Hedgehog series art to admire and scrutinize.

Movies revel in behind-the-scenes featurettes to load up DVDs and Blu-rays, but video games are frustratingly more secretive. A lot of it has to do with trade secrets and/or storing away ideas to maybe reuse in the future, but the result is often a raw deal for fans eager to learn more about their favorite video games.

These morsels of new Sonic Adventure and Sonic Heroes concept art from Sega give us a glimpse behind the curtain, and that’s terrific. And fortunately, again via Tails’ Channel, there’s more where that came from. Have a listen to some beta tracks from Sonic Adventure 2:
