I've been trying to sort out the best way to organise Vito's page so that the information doesn't end being a jumbled mess. The best thing I've been able to come up with so far is to break the history down into three sections by dates.
The events of Mafia II would be under "History 1925-1951", for the time between the games there is "History 1952-1967" and finally for the events of Mafia III and beyond there is "History 1968-2016". We can always change that final date if he dies some time before 2016.
Under the notable murder and trivia section I've broken it down by adding separate Mafia II and Mafia III sections and made separate galleries for both games. You can take a look at my Sandbox 4 to have a look. Unless anyone has another suggestion I'll go with that.
There's one thing on his page that I think needs to be addressed, and that's his service medal section. It just seems to look out of place no matter where it's put. Now there's a few issues going on with that. First off, the only medal that's mentioned in game is the distinguished service cross. The other three were all added based on what a soldier with his record of service should have received, but again, they're not supported in game.
I have no problem keeping them, but I would suggest they be moved elsewhere. Either place the entire section on the Military page, or remove the images and add them to trivia with the explanation that the other three medals would have been awarded to him.
If anyone has any input on this then feel free to reply.
