Economic RTS strategy, often seen in Age of Empires style games or Rise of Nation circles; also known as Powering in Blizzard game communities. Booming emphasises economic expansion and research (a.k.a "teching up") in preference to a large early force in the game. The objective is to a win by out-producing and out-teching your opponents with bigger and better equipped forces. They weaken short term defence for a superior long term economy which translates into a more advanced and powerful military. Booming players can find themselves vulnerable to early raids and rushes (depending on the game), but the payoff can be huge.
