the bigger difference is a crystal is a passive component and can be
thought of as a inductor/capacitor with a very high 'Q' (roughly, the
'bandpass' of the tuned circuit). an oscillator adds an active feedback
circuit to create an 'oscillator'
most of the time, on video games, the active component is two inverters
hooked in series with a crystal somewhere in the feedback path.
