Okay, so I bought the game about 2 years ago, and I am very happy to know that you can have it on Steam. I live in Brazil, so here KSP on Steam costs R$ 72,00 (About US$ 20,00). But the question is: How do I get it's Steam key, because i do not want to pay more than 2x what I originally payed for it: US$ 27,00. Help.
