The stage is well set! Hopefully the conflict between the individual Italian states (as opposed to just Piedmont vs. Austria) won't peter out quite as quickly as it did in real life- it would be a good story!
Am I being obtuse, or have you not already detailed how this is being played? Are you one particular faction, or is it going to be done as a story told from all sides (as suggested thus far...)?
Keep it up!
