Well..you learn to lie to and deceive others as well as uncovering those lies and identifying who's lying and who doesn't. It can get very frustrating tho the better you get. People will start doubting you in every round because you're too good at cosplaying a crewmate as an impostor and also at putting the clues together as a crewmate.
I'm not gonna talk about the rest, as there would only be QOL improvements to be made. The concept is similar to games we played in our childhood like killer in the disco or werewolf..just perfectly made for a pandemic :)

fun
