This suggests that the game is really a form of indirect communication. I may want to tell you about some truth of the human condition, but if I say it in conscious or explicit terms, it will sound too academic, too intellectual, and you won't hear me. But if I wrap my message up inside a game, and let you experience its manifestations rather than its intrinsic nature, those manifestations can penetrate your consciousness and work their way down deeper, where the true message can be induced from the instantiations and understood. Ultimately, the most profound truths can only be appreciated as part of the fabric of our understanding. If I insist on teaching you in my own words, you will never learn what I have to teach.
Experience is the only true universal language.
The truth inside each game is the same for all of us, but each of us must absorb it in his own way. That's why interactivity is so important.
