Quoted from purbeast:I only played Alien a few times while I was at Galloping Ghost and the only thing I can remember about it is how hard it is to see anything because it's so dark.
I own both (well, it's the original Alien which I own since the beginning) and I really like to play them. But without a doubt Godzilla is the better one. Alien conveys the movies atmosphere very well and has to be dark, and sound and movie-clips work fantasic. But overall game play is another level with Godzilla.
