Nah, Bethesda sucks because of the quality of the games they've been putting out. I liked Oblivion and Fallout 3 well enough, but they just seemed lazy. Oblivion/3 had way too many copy/pasted dungeons. Be it Fortresses/Ayleid ruins or Metro stations.
Stuff that would've been easy enough to remedy had they actually put some time into it.
Nope, never have. I'm sure it was great because I'm seeing no one saying anything bad about it, but it irks me when people say a game developer sucks because they didn't top the best in their series after a few games.
