First of all, you don't have to pay to install this game. just click the "No thanks, just bring me to the downloads" at the top of the menu, and whenever you run the game it runs it through steam.
Why thank you very much! Now that you have provided my the information on how to play it, the game now actually opens! Also, I haven't played it yet though because I'm replying to your very helpful comment. It's such a great thing to know that the internet has such a helpful community like this. So thank you for actually READING my comment, I thought nobody would read it because it would take years. I also thank you for even caring to reply to me, I mean you are just looking to download this game, and then you decide to look at the comments and actually help a person like me. So thank you VERY much, I'm now going to play the game, and god bless you.
