I know that in Burning Empires any player (including the DM) can apply binding constraints on character action based on the outcome of conflicts - Duel of Wits and Firefights. You can also change the character that you're in conflict with: "If I win, he gets the trait REMF." Or even something bigger: "He admits that I know the truth of the Lar-ta-Largi, the Path of Fire [religious doctrine], and that his interpretation is heresy."
There is a limit, though a subjective one, in BE. It's based on the margin of success of the conflict.
There are actually several limits in BE... no adding traits (advantages or disadvantages) to other's sheets without consent, no uninvolved main characters being affected, no "nerfing a success"... and the stakes have to be set before the roll...

In John Wick's
Blood and Honor and
Houses of the Blooded, EVERYTHING is up for grabs... if you have enough dice.
Since I've run a bunch of B&H, I'll use it... HotBlooded is the same basic system, but different terms, and slightly different character definition.
NPCs are usually introduced with nothing more than a name (personal and family), a Duty (think class) and rank thereof, and maybe one or two defined elements. When a task is resolved, everyone with a stake in the outcome generates a dice pool, and then splits that into two groups - dice rolled to decide the task, and dice reserved to make statements. He who rolls highest says whether the task succeeds or fails, and if he rolled 10+, gets one statement per die from their pool that they didn't roll. Everyone else who rolled 10+ gets one statement per 2 dice not rolled. Starting with the highest roller, and in descending roll order, each person with statements left makes one statement about the task or the scene. Then, if anyone has statements left, another round, and so on.
Each statement can be one action
by any character present in scene, one level of damage, wielder's rank in unnamed persons killed with a katana, one named person killed with a katana, one attribute of an NPC in scene defined, one statement by any character in scene, one named or a group of unnamed people added to or removed from scene, one level of a temporary trait added to any character in scene... but none are allowed to refute prior statements in that action.
Ideally, every statement relates to the task, or reactions to the task, or previously unknown conditions leading up to the current situation. Everything is required to make story sense, tho'.
For example, Ikugi Nobu is attacking Kanawa Ichiro over an insult in the tea house. He is attempting to cut him down with iaijutsu. Kanawa Yotsu, the local Daimyō, is also present, as is the unnamed matron of the tea house. Ikugi has Prowess 5, and Giri (duty) Bushi 3... He also has a reputation as a duelist at 2... so he's got 5+3+2=10 dice. He rolls 7, because he wants to assure that he can win. Kanawa Ichiro has only 6 dice; he's relatively certain he's going to die, but rolls all of them anyway, so that he might not. Kanawa Yotsu has but 4 dice in relevant abilities, and rolls only 2, just in case he gets lucky. Nobu rolls a rather unimpressive 11... Ichiro has a frightful 32 on his 6 rolled dice. Yotsu gets a 12... The order of speaking will be Ichiro, Yotsu, and Nobu. Ichiro keeps all his unrolled dice - but that's zero. So he gets to make the decision. Yotsu kept 2 dice, and gets to make one statement. Nobu, who rolled 6 of 10, has 4 dice unrolled, and not being high roller, gets two statements.
Ichiro decides he that Nobu missed the strike.
Yotsu states that Nobu is embarrassed by missing. Nobu writes the temporary trait.
Nobu has two statements. He gets to use one. Nobu notes that Yotsu is horrified by the uncouth public misbehavior of Ichiro.
If Ichiro or Yotsu had any statements left, they would go, but the don't, so Nobu continues. he has Yotsosama say, "There is no Kanawa Ichiro! Ronin, begone!"
It doesn't matter who was the Ref. If Nobu had won with a 37, he could have made it look like this...
N: I fail. (Statement 1 of 4

Yotsu stayed my hand.
I has no dice saved, so has nothing to add, despite a 36 roll.
Y: I will deal with my cousin to satisfy your Honor.
N: (Statement 2, putting words in Yotsu's mouth

Yotsu continues, "Kanawa Ichiro died here this night."
N: (Statement 3

The oba is in the Shōgun's employ as a spy.
N: The Shōgun knows by morning of the "death" of Ichiro.
Or, he could have instead done
N: I succeed. (S1

But Yotsu was also cutting him down.
Y: I am cutting down Nobu, too.
N: 3 unused wagers - I die with 2 more reputation... as an honorable death.
(There are benefits for other PC's in such cases.)
Note that the only reason he can cut down Nobu is because Nobu had him use iaijutsu to co-kill ichiro.
It's a lot of fun. It's very very very unlike playing D&D. Everyone is 1/3 GM, 1/3 actor, and 1/3 narrator.
Note the lack of character protection. Note also: they add (or in example 2, delete) items on character sheets. Both Ichiro's and the Oba's.
