Happy birthday!
Thanks for sharing the video! Great manners really makes for great impression, and manners will always be important in a game like Subterfuge. Be nice when greeting your neighbor, asking for drillers/outposts politely and don't force it, never get too mad when someone backstabs you, saying sorry or excuse me when you've done a mistake as politely as possible, etc. Manners alone can help you win the players' heart.
Or maybe everyone in the game could work together to take out a well-mannered player because he/she is too different from the rest.
