Yes – something resembling that trade-off has always been a part of the vision for the game. (:
The details won’t really become clear until Game 2, and I reckon it’ll be Game 3 before you’re managing any sort of blood economy at scale.
Hopefully at least some of you will have the patience to stick with me that long! (I can only imagine how the GRR Martin references will be flowing in another 5 years’ time…)
