Hey, this is the first time i've downloaded a game. I've downloaded Half Life 2, but I don't quite know where to go from there. It wants me to burn it onto a CD, but i don't have any CD's with enough space to hold Half Life 2. So I went and read somewhere that I need to find the crack for the game. The problem is that all i got is the game file and nothing else. So my question is, WTF do I do now?
