Fallout Tactics is a great extension of the Fallout franchise that's heavy on combat and light on storytelling. While Fallout 1 and 2 focus on character development, speechcraft, and open-ended objectives, Tactics is a straight-forward brawl.
Tactics uses an optional pseudo-real time system based on action points, flirts with vehicles, and retains all of the gory wasteland goodness from the first two games. If you've wanted to have fun with heavy weapons and dastardly traps while controlling a squad of customizable henchmen, this is the game for you.
If you're not interested in carefully planning your assault, unleashing the power of Fallout's ultimate weapons, and relishing the gory demise of your enemies, this game is not for you. If you are, then you'll feel at home in the Brotherhood of Steel.
