You can beat up Dan in gym class, after he gives you a wedgie.
It's not stopping anything, but nonetheless pretty safisfying.
Well, the whole quest series with them is full of logic holes, the player gets to beat up Christina and the Gopniks in the Residental Area. I assume that this is one of the very old quest series.
I mean, the game is structured in such a way that the player is forced to play in a way that actions = consequences = reactions.
And I think it also applies if you play a Sveta Sub then this quest series fits.
I personally think that if you impose actions = consequences = reactions on the player, then you should also do that with the NPC series that are a bit longer.
Because then the good game would become an outstanding game.
