The Meaning of Life, the Universe, and Everything.
I wish there was a way to go back to a particular Title Update, as lots of my redstone stuff has been broken since TU54 came out. I'd gladly go back to before that one, if I could, until they've fixed all the problems. Not sure I'd fare any better by going all the way back to TU1 though. My console would probably just re-download the latest update, and I'd be back where I started.
