I loved this game. This was the first DS game I bought of this style of game play, and it lead me to other great games like the Phoenix Wright series, and Trace Memory. I hope there is another; Hotel Dusk in the future. I played the game 2X's and was happy with the 2nd time through.
There are several out comes, but not endings. You have an effect on others, and they may like you or not depending on what you do. The second time through I got change and use the vending machines, and gave stuff away, and was liked a bit more, by some. It was a surprise ending, which I did not see coming. I was more than satisfied with this game and recommend it to anyone who likes adventure "point and click" games. It's not point and click, but very similar. No way to "die" only to get depressed and leave the hotel or get caught snooping and get kicked out. If you save, you can go back to before you did "wrong" and do it again.
It's fairly long, and too me longer than any CSI, Phoenix, or Trace Memory to complete. Well worth the price. Great Game. Hope you like it too.
