Stargate isn't quite the indispensable sequel that Galaga and Ms. Pac-Man became, but it does compare favorably to the original Defender. Actually that can be a good and bad thing. Defender is already an incredibly difficult game, and with even more enemies and more weaponry, Stargate can be downright overwhelming. To those capable of mastering Defender, however, Stargate's enhancements can be alluring. Either way, the game is at least as fun as Defender, and if it is equally as frustrating, it can be just as addictive as well.
