My theme is drawing
A game where two teams get different prompts, but have to draw on the same surface to get the other team to guess what their drawing is of. There would be a limit of how long one team can draw, so as to not just make a mess.
A game where players add lines to a sort of open-ended illustration, and the others vote on the best interpretation.
Pictionary-style game, but the drawer has to wear some sort of distorted goggles.
A game where players draw a mask of a famous celebrity or character, pass them to the player next to them, then have to guess who they are through a series of questions.
A narrative style game where the story is dependent on the best drawing a player conjures of their preferred plot point.
