As an OG TES and Fallout player who prefers Daggerfall and FO1+2, I can admit Skyrim was a good, if simplified, game and Fallout 3 was a fun adaption into 3D for the series. Fallout 4 is derivative. Taken alone it's fine but anyone could have created that with the wealth of assets and IP they were building on, so it's not a sign of competence. So sometime between Morrowind and FO4 is when they lost their mojo.
