3D Sonic The Hedgehog 2 is now on the 3DS eShop as of today (10/8/15). Taking the classic adventure with Sonic and Tails, making it 3D and compact. I personally own the first 3D Sonic game from SEGA on the eShop and found the game to be exactly the same as the original Sonic but with incredible Three-Dimensional depth. This sequel to the first game seems like it should've been out on the eShop a while ago, but that's OK, it's just good to see that they're not ONLY releasing one 3D Sonic game, that would be a shame.
Game on and Keep it Rehl!
