This game is divided into three parts, the first being least like the others.
You are in the army, and you are interested in your friend Simon. You have the opportunity to sneak more information about him, but it's not necessary, as you will have the chance to talk to him more later.
The game has a well-developed and smooth story, but it has oddly obscure puzzles. Most of these puzzles involve hunting around for objects, often finding them before yo know you'll need them. This is typical of a classic adventure, but odd for a story-driven one.
I found that the game frequently had trouble with alternate solutions to puzzles.
Overall, I would recommend this game, but it has some pretty heavy profanity in a scene or two. If that's not an issue, you should try it out. The first part is the most difficult, so I recommend a walkthrough to get through it.
