The Australian Classification Board ratedTails Adventure yesterday, suggesting an upcoming digital re-release of the 1995 Game Gear platform adventure. The rating is for a multiplatform game, with the author denoted as Sega Japan and publisher as Sega Europe.
One of the few games to star the twin-tailed fox as the solo hero, Tails Adventure looked a lot like the more mainstream 2D Sonic games releasing around the time, but barely played anything like them. As this video shows, it was a lot slower-paced with a Metroidvania-like emphasis on backtracking. It's also noteworthy because the Japanese and western versions had completely different background stories in their manuals - ah, those were the days.
