Two very different vessels yet tied together with certain similar art direction, which one would want your Captains patch labelled with?
The look and feel of the Nostromo is timeless, it dictates the personality of whoever its crew is, even the clinical Ash couldnt keep the grime off. I could easily replace myself with Ripley sitting back in that chair with a coffee and a durry watching ones and zeros glide by.
The Prometheus is an entirely different beast, seen in 3D, I thought it was incredibly sexy, just wanted to loaf around in my jocks and slippers and head to Waylans bar with the sound system up full blast.
Guess in the end for me its the Nostromo, bathing looks optional and theres more places to slack off. Bare in mind smoking is allowed on both vessels, cheers Rid.
