I've been a fan of CM/FM since CM2, and was distinctly unimpressed by FM2005. But I am glad to say SI are back on form - FM2006 is just simply put excellent so far - about three months in to my game and I am hooked once again.
I felt FM2005 was very non-responsive to your changes, but so far FM2006 feels like the things you change (or don't change) actually have an effect this time, not always what you had intended (which is a good thing!) but there is an effect of some sort.
It's easier to use, navigate, and to repeat what's above, like all previous versions to 2005, you quickly become immersed in the game. Even though the straw that broke the camel's back for me in 2005 is still there (I won't mention it in case other people haven;t noticed
), this is the only thing I have so far found to be a problem, and I seem to be able to quite happily ignore it this time!
Fingers crossed that it continues this way - good work fellas!
