What is it? Feel free to split them up by genre.
The reason I ask is because I was cleaning up my flat when I found a copy of Myst III covered in dust. I've only watched someone else play this game before now, and damn, these games aren't made to be easy, that's for sure. I get the feeling I'm going to get very frustrated later on. We'll see if I can stay interested long enough.
And yes, yes, I know, it's not as good as the other Myst games, but hey, I don't have the other Myst games, so there you go.
