Major League Baseball

Major League has official trademarks and uses copyrighted materials and is corporately sponsored. They take efforts to ensure a game is official licensed before it can use their logos and marks. There should be no need for the noncanon tag. Note that a MLB licensed game can be ported to another platform and the port might not carry the MLB license.

MLBPA is the Major League Baseball Player's Association. It is a labor union for MLB players. MLB & MLBPA grant licenses separately. The MLBPA guards the names and likenesses of their players. Unfortunatly, there are games with one license but not the other. For instance, a game can have MBL stadiums, teams, and "MLB", but no player names. But, as long as these are rare, noting it on the game entry and in tags notes should suffice. Of note, MBLPA was actually the 5th attempt to create a player's union for professional baseball. It was preceded by the Brotherhood of Professional Baseball Players (1885), Players' Protective Association (1900), Fraternity of Professional Baseball Players of America (1912), and National Baseball Players Association of the United States (1922). No baseball games are currently known that make note of these previous unions.
