hello! Thank you for the feedback!
This was a concern of mine actually. Generally the rules for this are "do what feels best for your group" but that may be too broad for a lot of folks.
For Chaos Cards they are always meant to be resolved as a group. Once the initial reveal of card (ie "Select *BLANK* before moving on") the table can decide what exactly happens. This can be done a few ways (having the card reader ask questions to specific players, taking turns answering questions, roleplaying, etc) but I do agree there should be some sort of default or that perhaps the cards should be structured so it's clearer.
