Jean Tirole's "The Theory of Industrial Organization" (1988) was the first cohesive text on game theory, modern industrial organization, and applied microeconomics, and I believe it remains the best advanced-undergraduate-level/early graduate text that I'm aware of in microeconomic theory.

Along those lines, I'd nominate "The Structure of American Industry" by James Brock (now in its 13th edition) for a seminal text on industrial dynamics that focuses on case studies and analysis.
