Well, re having some kind of journal to list all major choices on the playthrough, I do think it'd be a good idea. To tell you the truth, that's a feature I plan to add in a certain game about traveling vikingsYeah...and I'd only be telling the player what he already knew! Plus I'd probably balls it up! XD
I guess that would help people along the way to just load X save and look at the journal and say: "Oh, this is the playthrough where I've been only one third of an asshole and killed this character but let this one live"
