Enduro is an old Atari game that's now on the App Store, and it's available as a universal version for iPhone or iPad. Personally, I don't really remember this one (it's a racing game that's similar to Pole Position, though the big innovation was that you could race through different environments like fog or snow), but bigger Atari fans than myself might be excited to see that it's now playable on iOS.
The reason why Enduro is interesting, however, is that, as Touch Arcade reports, it's an unsanctioned port. Atari has already released several games for the iPhone
