Well I play this game all the time, and I never got around to actually playing through a dynasty and winning the championship until now...
Is there no championship celebration in this game when you win the title? I played two seasons and it didn't go into one after either series clinching win. They used to be pretty good in 2003/2004 and then 05 was kind of truncated, but it was still there.
Maybe I've just overpatched my copy or does it not have one?
