Give people the option to: read/watch, listen to your spiel, play, or a combination.
Remember to say: name, genre, 1 sentence theme/story, platforms, release date/"in development".
4) Do not chase after people walking away from your booth.
My fav line to say next is: "How can I help you today? Would you like to watch, hear my spiel, or play?".
Do not assume they'll take a card or force it upon them if they seem even mildly reluctant.
I'm not interested in your game.
This is not time for testing, this is time to meet people and tell them about your game.
else currently playing they can watch.
