Simplify using assumptions and Gamma[*]

Hi,

Since the Euler Gamma function is (n-1)! for n>=1 and n an integer, I
was wondering why

FullSimplify[Gamma[n], n>=1 && n \[Element] Integers]

does not evaluate to (n-1)! ?  Am I missing something here?

Am I using the Assumptions capability incorrectly?

Many thanks in advance,

Michael
