Football Manager 2005 is made by Sports Interactive. The company that made all of the previous CM games (from CM1 to CM0304). HOWEVER, last year SI split with Eidos with them going their separate ways.
SI kept the code and database etc from CM0304, but Eidos kept the name.
Eidos then teamed up with Beautiful Game Studios to make a brand new game with the name 'Championship Manager 5'
Football Manager 2005 was released on time by Sports Interactive achieving rave reviews and sitting itself confortably at the top of the tree.
CM5 has been plagued with errors (as expected) and its release date has now been put back to March/April time.
Into my heart an air that kills
From yon far country blows:
What are those blue remembered hills,
What spires, what farms are those?
That is the land of lost content,
I see it shining plain,
The happy highways where I went
And cannot come again.
