It's not to say Starcraft isn't a challenging game or there isn't any depth to it, but I am saying if 4 pooling is considered deep stuff, you have to realize that something like chess is on a completely different level.

I'm quite sure you could put all you would ever need to know about Starcraft strategy into a single 300 page volume, whereas there are entire libraries full of chess books, databases of millions of games and 3300-rated computers slugging it out constantly, and the game still hasn't been completely exhausted yet.
