Joseph = First person shooter
Vittorio = Mon games
Louise = RPG, obviously
There was actually a conversation over at SB relatively recently about the concept, and it was concluded that Joseph actually has the power of Princess Maker (specifically,
this take on it). His target is, of course, Tabitha.
It's not that he hates her and wishes her death, he honestly tries to do good by her and make her the best person she can be. It's that, well, it's Joseph Shinkicker, not the best choice to raise a child (especially after the trauma induced by playing Long Live the Queen with Tabitha's mother).
He really tries, though.
Joseph: Sheffield!
Sheffield: What is it now?
Joseph: I just realized a terrible thing! Tabitha literally has zero score in Conversation and other social skills!
Sheffield: Well, you did insist that she do nothing but slay monsters and learn combat and magic since she was eleven. That probably has something to do with it.
Joseph: Hey, it worked! Those magic lessons aren't cheap, you know? And we can spend only five hundreds coins on her per year for... some reason. Did you find out where all of our taxes go?
Sheffield: Yes, sir, your pills.
Joseph: Purple are my favorite! Anyway, be it as it may, I've found a solution to our problem!
Sheffield: Dare I ask what it would be?
Joseph: Oh, it's simple, really! We just have Tabitha work in my favorite bar for a few months. Maybe a year.
Sheffield: You mean that bar with weird fumes?
Joseph: I always feel giddy after visiting it, and I think Tabitha can stand to smile more.
Sheffield: *sigh* Alright, I'll make changes to the schedule.
Now, Vittorio I would pin as an RTS type of guy. He already summons tanks out of nowhere, after all. Now he probably has to throw raw materials into the portal firs, though. He also constantly hears mysterious voices telling him "we require more minerals."
Poor Tiffania is relegated to what, in this paradigm exactly?
Darkest Dungeon, duh.
She can grant her orphans basic proficiency in a number of classes and send them to rampage across the country and gather loot. They tend to die a lot, but there is always more orphans (mostly because the old ones make them, granted).
Gathered loot goes into upgrading the orphanage and building a few facilities, like asylum.
