The Game Stick has no cartridge slot, or an input for a second player controller or Zapper. This means that some of the games included can't be used because of the need of a gun (Duck Hunt, for example). The system includes 76 games, but some of them are repeated or are graphical hacks (Teletubbies, for example, is just Mario Bros. with graphic changes). The system includes only A/V cables. It uses 4 AA batteries.
