Baseball Mogul begins in any year you choose, from 1900 to 2006 with the full roster of your favorite team -- or an entirely fictional team of your own creation. As General Manager (GM), your job is to build the best lineup of players to take your team to the World Series. You can make complex player trades and sign players to multi-year contracts as you build your team, but you'll have to compete with the other General Managers, and negotiate with the player's agents.
