I haven't actually played V5, so my only experience with it is by skimming the rule book and watching LA By Night on Youtube.
My impression is that it's a significant improvement over earlier editions, particularly the Hunger system. In previous editions, you had a Blood Pool of 10 or more points depending on generation. When you used blood, you just crossed out points and when you drank you just filled it up. Functional, but a little dull.
In V5, you instead have a Hunger stat that ranges from 0 to 5. Drinking a small, safe amount of blood lowers it by 1, and drinking a larger amount of blood from a single vessel can harm them. Depending on the blood's quality, your hunger can't drop below a certain value - things like blood bags and animal blood might never take you below 2, and the only way to reduce your Hunger to 0 is by entirely draining your victim. There are also rules for how the mood, or Resonance, of the vessel can affect you.
Calling on the power of your blood requires a Rouse check: roll a die with a 50% chance of increasing your hunger. This creates an uncertainty regarding how much power you can call upon, instead of the plain numbers of earlier editions. As your blood potency increases, some things become easier to do so you might roll two dice instead, with both having to be failures in order to increase your Hunger, or you get increased value for your Rouse checks (healing more, getting a bigger bonus). Blood Potency servers some of the functions Generation used to do. It is connected to Generation, but each Generation has a span of possible Blood Potencies.
When you make a skill roll in the game, you replace a number of dice with Hunger Dice. They work mostly like normal dice, except:
- You can't spend Willpower to reroll Hunger dice (normally one point of Willpower lets you reroll three dice, but they can't be Hunger dice)
- If you roll a 1 on any of your Hunger dice, and your roll is a failure, you have gotten a Bestial Failure. Either the Beast manifested in a way that caused you to fail, or your failure made the Beast manifest. This can result in a Compulsion to act in a negative fashion for a short while, give you a point of Hunger, or some other negative effect.
- If you roll two 10s, and at least one is a Hunger die, you have scored a Messy Critical (normally two 10s is just a critical, which counts as four successes instead of two). This means you succeeded and probably overkilled in a way that can threaten the Masquerade, or temporarily lose a dot of an advantage (background) because of your mess. You didn't just knock the guy out, you tore his head off. You didn't just realize something on a knowledge-type roll, you went on a long rant that alienated your allies. In your attempt to intimidate someone into letting you pass, you bared your fangs and snarled at them, sending them packing but showing your true nature. Stuff like that.
I would absolutely
love to see a Mage 5th edition that based its Paradox rules on V5's Hunger rules (but with Weird Stuff instead of monstrousness).
