Atari is teaming up with Plaion on a new retro home console after finally taking a mulligan on its last one. The Atari 2600 pays homage to the original Atari 2600, which delighted children of the disco era starting in 1977, although this remake is based on the four-switch model from 1980. It plays both Atari 2600 and 7800 games. However, most buyers will want to track down physical cartridges as the retro system, which requires them to play, is only bundled with a collection of 10 titles that lacks system standouts like Pac-Man, Frogger, Space Invaders and Pitfall! The throwback console has been "lovingly recreated to the same specifications as the original," although it's only 80 percent of the size.
