Strategic Depth (n)
The complexity of the strategic space that the game creates. Basically, it is a measure of how many viable strategies there are, how many ways they can interact with other strategies, and how many decision branches there are that require players to choose between strategies.
Usage: Chess has a fantastic level of strategic depth for such a fundamentally simple game.
Comment: Strategic depth sounds great, but there is such a thing as too much of it. Don’t overwhelm people who are just out to have a good time blowing shit up. I honestly don’t play Starcraft very often – a game with incredible strategic depth – because it is so mentally stressful. And I usually like intellectual challenges.
