I'd like to see some examples of Feeding Dependency. It affects a few character types, but lacks a detailed example. Also, some of the effects seem odd or unintended.
After reading it, I'm not quite sure the intent behind the rules for the stress track actually is. The stress track seems primarily about figuring out whether the character has been taken out by hunger. Based on searching the pdf for the word hunger, you only take stress after a scene is finished, not during the fight itself. That doesn't completely track with the books, where we often see Susan, Thomas, or Lara feeling their hunger mid-scene.
Here's my thoughts on how the rules-as-written might be used, but I'd really like to see clarifications and examples:
1. Mid-scene problems are going to come from Discipline checks or compels on a high concept. Nothing actually causes hunger stress during a scene.
2. Post-scene, I roll discipline vs a target based on the powers I used during the scene. So hunger stress is really about the NEXT scene, not the current one.
If I win the roll, I WIPE OUT my hunger stress track. Because the only thing that causes stress on this track is FAILING an earlier post-scene hunger check, I'm using my discipline now to eliminate hunger incurred in an earlier scene. That seems REALLY weird.
Also, it might be manipulated by the player. Come up with a scene with minimal use of powers and you can easily make that discipine check.
3. If I take hunger stress, I lose powers based on the stress taken. 2 stress = -2 powers. If I take stress over two consecutive fights, the results will be cumulative. 2 stress + 3 stress = 5 points lost.
I suspect the intent here is to encourage players to go for a consequence instead. ("insatiable hunger").
One possible continuity problem is that some of the vampire powers they can lose are things we've never seen them lose in the books. It is more common that their powers become harder to control. For example, in the rules as written, white court vampires could lose their ability to incite emotions. The reverse is always what happens in the book -- Lara or Thomas is not someone you want to be around when they are hungry. They lose the ability to control themselves. That *could* be modeled as a consequence that immediately gets compellled...and compelled...and compelled...
4. Once I've lost powers, they recover at a rate of 1 point per scene I miss, or all of them after a kill. However, the stress track clears completely after missing a single scene. Cumulative stress on the track is more about avoiding being taken out by hunger than about recovering powers. Realistically, before being taken out by hunger, most vampires are going to be out of commission because they've lost their powers, which seems odd. Also, losing powers means they have less powers to use, which means they'll make the discipline check more often. So, actually getting taken out by hunger is hard.
