not everything got implemented so far. i'm not sure if there's a talking head for every character planned or if there are 'supporting roles' with no talking heads. i think most of the ones i've seen so far have had no voice. overall, the acting is good compared to professional actors, and some talking heads are even better than the original ones (e.g. loxley had no facial expressions at all in the first fallout). it's a pity (or, as the polish say, the sorrow squeezes my ass) that it takes so much time. i would like both fallouts with the talking heads mod. if i were richer, i could invest say 10k bucks in it (although i don't know what difference it would make). a few additional mods make this game playable to this day. although personally i would add my reservations about all these restorations, mainly about the fluidity of the plot and the credibility of the game. the mechanics themselves will always be archaic, although significant progress has been made with sfall
