I wasn't interested in the game before reaching halfway of this article, but wow! This game looks great and full of symbolism (even though I spoiled it on myself by reading this.) Though I agree it might bore some players...
Sea of Solitude reminds me of Never Alone for some reason. (I know they're too different but...)
I've never played Never Alone. I am going to have to look into it. You are right about the game being full of symbolism. There is a lot more to it than I put in the two posts about it.
