haven't played fable III yet but you would definitely be getting your money's worth from new vegas if you were to buy it content wise. i've been playing new vegas off and on for a week now and i've still got a ways to go to beat it i think. there's a ton of stuff to do, even more so than fallout 3 IMO. it is buggy in a few areas, and i had some freezing issues first starting out, but the pros still outweigh the cons in my book.
