There was a time when Sonic the Hedgehog 2 -- now available on Xbox Live Arcade -- was accompanied by much fanfare and bizarre commercials. Alas, that time is gone and we are left only with tiny little announcement posts like this one. Still, the quality of the game hasn't been diminished. Actually, in light of Sonic's more recent console endeavors, the quality may actually have increased. Sonic the Hedgehog 2 improves on the first game in a number of ways. It introduces Sonic's bosom buddy Miles "Tails" Prower, split-screen multiplayer, and Sonic's trademark spin dash. It's definitely one of the best games in the series and worth checking out.
