A note on starting Hunger. While it makes sense for newly rolled up PCs to start with a Hunger reset, the rules have it that the only way to get to 0 is to have imbibed a mortal to death.
So what I suggest is, you all start at Hunger 1, unless you feel in your backstory that you've definitely killed someone recently through blood drain, then set it to Hunger 0. Edit: If you have Prey Exclusion of some sort, let's take that as indicative that you've been trying your best to draw the line somewhere, ie, perhaps you haven't killed, yet. And so you start at Hunger 1.
After which, don't forget to adjust for these starting Rouse checks.
Mechanically, Hunger gives Hunger dice, which affects your die rolls by making them riskier in having the beast side of you come out more.
(And as mentioned before, V5 doesn't do blood pools like previous editions, there's no need to drink up to fuel your powers.) Think of the tension as, the more you do vampy things, the more vampy you're likely to behave.
I'll talk about Resonance next.
