Are they all the same people who made those better games? A studio is only as good as the people working there, otherwise it's just a name. I'm pretty sure Obsidian isn't the same. Also I believe at least one of the Bioware honchos revealed himself to be a regressive leftist, which - in isolation - didn't interfere with creativity at the time but after TDS set in his cult became mainstream and all culture became a vehicle for The Message.
