MLB Power Pros.
Can't say how many times I "beat" it... however I made 5 teams of Success mode characters.
Which means i took 125 players through the RPG mode.
In addition I played MLB life mode a lot and Success mode.
In fact i'm in the process of playing one of my created teams through a season mode right now. 3 Characters through MLB Life mode....
and making 2 more teams. One of US presidents, and another of Famous tyrants.
