would be good if you make inventory by waight like someone can carry 10 kilograms not by slots. example : you take iron ore it weights 0.2 kg and you can cary 10/0.5=20
also you could increase you weight and it would make you move faster or slower
it was in one game named fallen earth online nr3 is kilograms

yeah i always liked the uo (and the similar one in darkfall) inventory system, no slots, could be positioned anywhere in your pack and you were limited to 255 items or about 400 pounds at max strength with your speed starting to slow around 200 pounds.
