Despite the notion that every game they make besides TES or FO is utter garbage but w/e, everyone is entitled to their opinion.
What games besides TES and FO have they made in the last 10 years (since Morrowind)?
Once Morrowind was released, they went right to work on its expansions and Oblivion. Once Oblivion was released, they went right to work on its DLC/expansion and Fallout3. Once Fallout3 was released, they went right to work on its DLC and Skyrim.
