Okay, I think it can be quite difficult to understand what ASA is exaclty ; there aren't so many medias that speak of the game and the screenshots don't always tell much. So I have good news, PlayDB posted a video of the beginning of the game on their youtube channel - a video with a lot of speech. It's 20 minutes long so you can make yourself a good idea of this space Adventure !
PlayDB - ASA: A Space Adventure :
The video starts from the main menu of ASA and you can see all the beginning after they click on "new game", from the opening movie to the very first steps on the Ark : opening the first door, visiting other areas. Be careful though, it will show you the solution of some puzzles.
The comments of the video seem very funny (although I didn't understood everyting as I'm not english), and they make it very lively and interesting to watch.
Thanks to PlayDB for their work, that was much appreciated, and a very good surprise ;)
