This Party Sucks is a relatively intense storytelling game about processing a bad breakup, but which is nonetheless sympathetic to both the messy protagonist and the players.
It's 13 pages, with an easy to read layout, and the instructions are extremely clear and easy to follow.
It's also got a unique format, and as a group you'll be shifting roles periodically. This helps a bit to diffuse the emotional intensity, since the character being a shared space helps keep people from feeling acutely that "this is me."
It's got reasonable safety mechanics, along with a really cool soft mechanic where you can tap a card to show that something feels personal to you, but you don't mind at all that it's in the story. Being incentivized to signal this way makes it easier to avoid running into problems in the first place---but you may also want to pair this with x-card or something more forceful in order to have a way to throw the brakes on anything that you didn't define as a no before starting play, but that you've realized you def don't want to play through.
Overall, This Party Sucks has a hopeful tone and an interesting atmosphere. If you like intense, character-focused and relationship-focused explorations, this is a good choice, and it's very solidly written.
-The Palette. It might be better to list only everyone's NOs first, and then list everyone's YESs. Otherwise you run into a potential issue where someone drops a YES that the next person actually wanted to make a NO.
-Are all Party Prep Moves are performed before a party? I wasn't 100% sure, but this seemed likely.
