In several episodes of actual play podcast Friends At The Table, GM Austin Walker will ask a question like "what are the verbs here?" That is, what things might you want to do here; what shape is this possibility space? Often in games, this list is very short.
I played Kickstarter boardgame Ravine four times this weekend. Sitting at the table with my Minecraft raised son and arts & crafts mum, we had a good time with its post-disaster collecting/crafting gameplay. One of us even got rescued (once). But when the game told me to sing, I stared blankly at the table top.
