Legacy, Anthology, Quadrilogy or wait for Prometheus box set?

Go for the alien anthology (blu ray) set. The anthology is, without question, the most comprehensive set available. You can always just purchase the prometheus set by itself.

It's hard to say. I have the Alien anthology which has alot of extra features. I also have the first Alien DVD release which has extra features that are not included in the Anthology. I think it's just another way for Fox to make more money! I think your best bet, would be, to do research on the internet, as to which has the most features.

,.......Santa will be on his way soon ,,so get the list going and get them all

I think the ultimate one including Prometheus will take a really really long time since Fox already planned sequels in 2014 or 2015. Its pointless to add the first film of the Prometheus series into the Alien series when the Prometheus sequels aren't even out yet.

You know Fox would love if you just purchased all of them just to cover your bases.

These things always evolved when a new sequel comes out Original/ Original Special edition Original/ Sequel / Original Special Edition / Sequel Special Edition / Original & Sequel Special Special edition Prequel / Original/ Sequel / Original Special Edition / Sequel Special Edition / Prequel Special edition / Prequel, Original & Sequel Special Special honest its even better if you buy them all together even though you already own them edition
