This is yet another NOAC-based product licensed by Atari Interactive that includes facsimiles of classic Atari games.  Graphically, most of the games looks similar, but on closer inspection, it's clear these are conversions, and poor ones at that.  Some of the games are based on the VCS versions, some on the 7800 versions, 1 is a unique version, and one (RealSports Volleyball) isn't based on the VCS version but rather an Intellivision game!  Here's a brief description of each and some of the issues with them:

Adventure looks similar to the VCS version, but that's about as far as it goes.  Someone noted that when pushing 2 objects between 2 screens, 1 of the objects will disappear.

Asteroids has the same issue that the version on the original Atari Flashback has - when you stop thrusting, you immediately stop; your ship has no momentum, which it most certainly should since it's in outer space.

Breakout is similar to the VCS version, but it plays with a joystick.  It's worth noting that 7 of the 10 games originally used either a trackball or a paddle controller, which is all too common a mistake other reissues of these games have made.

Canyon Bomber is similar to the VCS version, but hardly a title you'll find on any top-10 lists.

Centipede is similar to the 7800 version, but less enjoyable to play.

Crystal Castles is similar to the VCS version, but with different music at the start of a game and a slightly-different aspect ratio.  Although someone spent time trying to recreate the title screen, the letter spacing is different enough to reveal this isn't the original game, even before you start playing.

Millipede is similar to the VCS version, but like with every other poor conversion, all the polished gameplay of the original is missing.

Missile Command looks similar to a hack that was done in 2005 to include all 3 missile bases, but the graphical glitches and flickering that's common with most NES games are soon revealed in gameplay.

The packaging states "RealSports Volleyball" and the title screen simply says "Volleyball", but the game itself looks like a conversion of Intellivision's Spiker Super Pro Volleyball.

Warlords is, as far as all the other games go, looks the closest to the original VCS version.  Alas, you're stuck with using a joystick, when it was designed for use with a paddle.

This joystick system is proof that Basic Fun didn't learn from the reaction they received over their keychain games 11 years prior, as the conversions aren't much better than those found on Atari's original Flashback system.  Your time and money is better spent acquiring copies of the originals.
