Has Another Player’s PC “ruined” the Tone of a Game for you?

[AttilatheYeon]

It is supremely irritating to me when a player just absolutely MUST play this one idea they had, regardless of how poorly it fits or any other circumstances, even if the idea isn't a joke (although it usually is) the total refusal to make concessions is a red flag to me.

I find when a player absolutely has to play this goofy idea, it's because they don't get to play much and have psyched themselves up for this game and character. This is the biggest strength of the session 0. It gives the group time to either talk that player out of the bad idea or drop them.
