In Fallout The Role-playing Game, by Modiphius Entertainment, on page 137, it describes power armor and there is a table. I noticed that none of the costs make much sense (really, only 150 caps for the 4500lbs power armor frame, T-60 power armor pieces cost the same as the prototype X-01 pieces, etc), but what really confuses me is how heavy T-60 pieces are. According to the descriptions, T-60 was invented and was just starting to be mass produced and deployed before the bombs fell, but X-01 was still in prototype. For some reason T-45, T-51, and X-01 all have similar weights (all under 200lbs for a chest peice, for example), but T-60 pieces are all 700lbs+ (750 for a chest piece).
Is this a mistake? Is it possible that they got the tables backwards, and switched weight and cost? Even so, why would T-60 cost so much more than the better prototype X-01 armor?
