Deserting the Championship Manager name was at first a difficult decision, but after researching what actually happened, i decided Football Manger would definitely be the better game, and i was right.
''When SI split from Eidos, SI Games kept the base code, the game database and programming of the game, whilst Eidos kept the name "Championship Manager" and its interface.''
With that knowledge in mind, it was very easy to choose SI and Football Manager. Also FM 2005 was released about 4 months before CM5, bad move by Eidos.
