This game is amazing, diverse in so many ways, with an attention to detail and a very well developed world that makes this game really immersive. There is a strong plot, a whole environment, and fully fledged characters with backgrounds that tie into the plot.
This game doesn't just have potential. It had potential, multiplied it, and is now blowing our minds with it.
The 'gallery' where you can see which sex scenes you have unlocked is a really interesting idea (as is the link to the wiki that provides help in unlocking more of those scenes), and adds further to the replayability of the game, which the multiple choices already increase!
To anyone still hesitating: give it a try! Just don't plan to do anything in the next few hours, time will fly faster than any starship once you start playing!
