I've enjoyed all BioWare's & Bethesda's games that've come out... even Battlespire. And in the end that's all that matters to me. *shrug*
Sure there has been a downward trend going Daggerfall - Morrowind - Oblivion, but I'm optimistic Bethesda will redeem themselves with an eventual TES V... considering they brought out Broken Steel in reaction to outcries considering FO 3's ending, this gives good hope that a lot of Oblivion's design choices will be given a second thought and hopefully reversed.
