Yes, this game was very innovative when it came out. It's clever and original and smart and all of that stuff. But after playing this half a dozen times the game seems to somewhat stagnate and play itself out the same each time - I suspect you don't really have as many valid choices to choose from as their first appears.
It's hardly an exciting game, and fails both as a rip roaring good time and as a true brain burning contest of wills. Ultimately this is a game that really impresses the first time you play it, but once the sheen wears off it becomes rather average.
