Improv (as I’ve learned it) is taught by learning various games, where each game develops a certain skill. Eventually one builds a repertoire of skills and is able to combine a bunch of them and so some impressive stuff.
However, some games I find to be a ton of fun just on their own. (Which is probably because I’m naturally best at them.)
What I also like about the “Because I said so!” game is that if someone asks you about improv, it’s fairly easy to explain the game to them and get them up and running DOING some improv so that they can get a feel for it.
So here’s my understanding/explanation of the improv game “Because I said so!”
