It's a solid tactical game, but it could have been a lot better.
While the first two Fallout games were set in post-nuclear California, Fallout Tactics is set in the mid-west around Chicago. You are a new recruit of a splinter faction of the Brotherhood of Steel, and you actually create your character using the S.P.E.C.I.A.L. system from the first two games. While this is all well and good, I was disappointed that my character couldn't really interact with anyone like in Fallout and Fallout 2. Your character is essentially mute, and gets involved in one sided conversations with NPCs. The storyline is pretty dull, and uninteresting in general, and focuses on an army of robots rising in the west that are bent on cleansing the Wasteland for a new civilization, yay.
The gameplay is pretty straightforward, you run around with a squad of recruits and perform missions for the Brotherhood. These missions generally involve wanton destruction, but if you're a big fan of the combat in Fallout then I suppose that this could be called fairly good. You can actually switch between real time, and two variants of the traditional Fallout combat system. Being able to switch between three battle systems is a great feature, but I generally stuck with real time since combat is a lot more frequent in Tactics than it was in the first two Fallouts, so turn based combat would become an exercise in tedium.
Graphically the game looks like high resolution Fallout with better coloring. So visually, the game is fairly nice looking, for a 2D Isometric title. Unfortunately the visual design practically does away with the retro-50s look of the first two games, and goes with a more modern and futuristic design. As far as Audio goes, the sound, voice acting, and music is nothing special. I wasn't expecting remarkable audio from a Fallout game, anyway.
I can't think of a good reason to recommend Fallout Tactics. It's not a bad game, but it's not remarkable either. The game could have been a lot better if they used a dialogue tree system like the first two titles, I'm aware that Tactics isn't an RPG like its predecessors... but that doesn't mean they had to make your character a mute meat shield. Tactics is a good buy if you enjoy Fallout's combat, though; personally I thought the combat was one of the least interesting aspects of the series, but at least now I can say that I played and finished Fallout Tactics.
