There is a lot from the UO that hasn't been done, like the story playback which includes little notes talking about what's going on in the scenes. Some are obvious, or just talking about changes in dialogue for different characters, etc., but others might be more interesting. But those are tiny little passages, so picking the good ones and getting through them doesn't seem like too much hassle.
The profiles and timelines would be worth doing, since they can have some interesting stuff (although as in one of the threads Ravy posted, not all applicable now with the Compilation).
Do we have (or can we come to) a consensus as to which one we'd be going for?
