Pressing ESC (or spacebar) will not allow me to skip the Intro movie or any dialogues. I have to watch the entire intro movie everytime I launch the game and also have to listen to every sentence in the game. Pressing spacebar doesn't seem to skip dialogue. The walkthrough says that ESC should at least skip movies and intro for game. Can anyone help?

Your Esc key may have issues - It works just fine for me.

But it works fine in my other games.

Maybe you should uninstall and reinstall the game again. Something may have messed up when you installed it.
