Oh my, look what I found... Why are these ideas buried so deep in the Suggestion section? The element of food and hunger would make a big difference to the gmae, this should be discussed more.
I would like food to be introduced. Like many people already said, it could give you a little bonus, and work like drugs...
Making different kinds of meat (from different critters, which would mean more art work, descriptions and the like) would only make sense if they made different effects. And yeah, all food should be radiated. But why only creatures' meat? why not add effects to the good ol Iguana-on-a-stick, Spaghetti, etc...?
Cooking might be too much.
Food sanitizer? come on! What the fuck is that anyway? how does it work? It's just another WTF item from Fallout 3 (like Pipboy 3000).
I would like a hunger system, but it seems most people are against such a thing. IF a hunger system is implemented, why not a thirst system as well? we could use the old Nuka cola and Water flask for this. We also got the Water bag in FOnline. Maybe introduce the different flavours of Nuka cola from Fallout Tactics? Nuka Cola Quantum would be out since it was "sold in DC area only" (but do we really have to respect a "Fallout 3 canon"? must we let such a thing as "Fallout 3 canon" exist?)
This is a very interesting discussion.
