Hmm, how many? I guess one or two really, with a few variations depending on what choices you've made through the route.
I suppose it also depends on what you would consider a 'bad' ending. The outcome of the peace talks are separate from the outcome of the relationships, so you can have a good outcome in one, and a bad outcome in the other - in those cases, only you can decide if that is a bad ending or not. ^_^
Many thanks for your support (and patience ^_^)
