When the child interacts with the characters, is the grandparents role more as a guide for the child exploring the environment? Does the grandparent received feedback/hints as to possible branched routes through a linear story that occur when the child interacts with the characters/objects? I see the grandparents role as one of a guide? In a way, all the grandparent needs to know is hints that, for example, where a key is hidden and where in the story that key comes into use … the child is then free to explore everything and yes, if the unicorn wants to try on roller skates … the unicorn can try on the roller skates … but occasionally, the child might interact with the unicorn and it would do something unexpected … feed the unicorn a particular mushroom and it hops into the air and farts out a rainbow! Another type of mushroom might have no effect at all … or another type of mushroom makes the unicorn’s horn flicker as if it’s a radio antenna receiving a secret message from the queen of the candyfloss fairies … cue small video video clip … grandma see’s what the objective is … how it can be achieved .. but the child just enjoys the wonder of the experience no?

I can sign in to my grandkids’ Minecraft server and interact with them by either helping to build a house or castle, or blowing up what they have built or filling their rooms with cows, pigs etc. Great fun!
