From Out of the Park Developments:
Out of the Park Baseball 13 is a baseball simulation that GamingTrend calls "the most complete baseball simulation on the market". OOTP offers unparalleled flexibility in creating your own baseball world. Play solo with a baseball world of your own creation: make a simple, 8-team league, play a typical major league game with complete 2012 rosters, create a historical league with real players from any year between 1871 and 2011 or build an enormous world with baseball leagues in multiple countries. For the ultimate challenge, join an online league and test your mettle against other human players. OOTP 13 is the closest most people can get to being the general manager of a real baseball team. Handle GM tasks like drafts, trades, scouting, waivers, team finances and personnel. Negotiate player contracts. OOTP 13 also has a vibrant and helpful user community, and an active one that creates a vast number of user customizations that you can use to further improve your gaming experience, including special roster sets, logos, and player images.
