One thing I didn't like in oblivion was that bread, venison, boar meat, etc. were just more alchemy ingredients. I never bothered to do any more than grabbing all the plants in the wilderness and spamming potions, only taking the good ones and selling the rest. Considering how much harder it was to aquire those ingredients, they should have been more special.
I am just playing new vegas, and I like the way chems and foods are so different from each other, clearly defined. I don't want foods to be alchemical ingredients, I want them to be a seperate class of items that exclusively provide health and fortify effects, as well as reducing the hunger variable in hardcoe mode. Give me a reason to cook, Todd.
