well,
several days ago, during one OBE trip,

i saw a game system (idea) that maybe haven't yet develop on our world.

it uses tablet, it is sort of magic like RPG game,

you collect woods, then you use your hand to write magic spell (word or sentence)

it will uses the log you collected and you lay them on the tablet, (follow physic rules).

then you need to say the word, then the wood log will get burn and magic releases.
