Morrowind had a few food items like crab or rat meat and bread, Oblivion had tons of food items. And the Dark Brotherhood appeared in Morrowind and Oblivion before the first line of code for Fallout 3 was written so calling them Talon Company is completely stupid. I'm guessing you never played the previous Elder Scrolls titles.
Eating food did not heal your damage in Morrowind or in Oblivion. That only worked in the Fallout games, as it suddenly does now in Skyrim. You must have never played any of the ES games, or the Fallout games, or you would know that. OTOH, I have played both Morrowind and Oblivion, as well as FO1, FO3, and Fallout Tactics.
On the subject of the Dark Brotherhood, they never try to assassinate your character in Oblivion, and only did in Morrowind as part of the Tribunal expansion as part of the first quest of its main quest. They do they show up with a note on their body written almost exactly like the ones you find on the Talon Company assassins who constantly try to kill you in FO3. Obviously you do not know that either. So before you call something stupid, you might actually try to learn what you are talking about first.
