I own a copy of the Complete Works, but somewhere along the line I picked up an aversion to reading plays on my own time if I haven't seen them first, so if it's not listed above I haven't read it either.

Same here. (Although not exactly, since I don't have the complete works, but have a collection of a lot of the plays, but I can't read the ones I haven't seen. Hence the BBC Shakespeare odyssy of a couple of years ago!)
