Why do you think nobody tried to make a remake of Daggerfall using the graphics of Oblivion or Skyrim? I have never played it, but I read the game is quite good, apart from the graphics. So, while Morrowind has been remade for Oblivion and Skyrim, why do you think nobody tried the same with Daggerfall?

daggerfalls too big and buggy

Morrowblivion and Skywind aren't remakes. They are mods/tools.

Mods that aren't allowed for discussion since they break Bethesda's rules on transfering assets between games.
