At last, you now have a simple way to play hordes of classic Atari games on your PC without resorting to third-party emulators: as promised, the Atari Vault is now available on Steam. The Windows-only collection lets you play 100 arcade and Atari 2600 games, such as Asteroids and Crystal Castles, in an environment that strikes a balance between nostalgia (such as borders that mimic arcade cabinets) and modern-day conveniences. That includes online multiplayer play, worldwide leaderboards and advanced controller support -- Valve's Steam Controller will even mimic a trackball to give you a more authentic experience in Centipede or Tempest. The Vault costs $17 on launch (normally $20), so it's just inexpensive enough that you can relive the good old days without feeling regret afterwards.
