Strangely enough (... NOT!) every time a new game relies on graphics so much that the slightest glitch is a tragedy, my interest in it fades away...
Don't get me wrong, I like good graphics, but IMHO they must always be the final touch on games that are very good in every other aspect.
Also, pushing graphics too much and having therefore hiccups gives a much worst impression than maybe less detailed, but more smoothly running ones.
