The sequel to Sonic the Hedgehog 4: Episode I has finally arrived for download on PlayStation Network, XBOX Live, WiiWare, and PC. Episode I was met with a lot of mixed reception, most notably the less than stellar physics engine. Sonic could not reach the same speeds that could be seen in the Genesis games. The developer’s goal was to fix this problem in the sequel, Episode II. Now that it’s here, Episode II is a good improvement over the first game in many ways.
