One of the strengths of OOTP is that it offers multiple ways to play the game. You can create your league and simply watch it evolve by simulating long periods of time. Maybe you want to act as a general manager and build your franchise via trades, contract negotiations, or through the first-year player draft. Or you can dive deep into managing and call the strategy for every pitch and at-bat from the dugout. And of course, you can tailor all of this to your individual style of play.
