Why are Pills are so big and heavy? First, in real life a pill is tiny , but in Icarus you can only stack 10 pills in a slot and 10 pills weight 2,5 Kilogramms. That are a quarter Kilogramm per Pill! That is about the weight of a steak. A stack of 100 and a weight of 1 Kilogramm for 100 Pills would be more realistic.
