Take a trip to the ol' eShop
Following last week's debut of 3D Space Harrier and Super Hang-On on the 3DS eShop, another pair from the Sega 3D Classics line is available: 3D Sonic the Hedgehog and 3D Altered Beast. These are priced at $5.99/€4.99/£4.49 a piece.
Now, Altered Beast is good for the obligatory "Wise from your gwave!" joke, which I'm glad to get out of my system. Sonic, on the other hand, I wouldn't mind playing again -- particularly now that I'm familiar with the extensive amount of work M2 put into this game.
You can (optionally) spin dash now! Crazy!
