Actually you told me to buy the game to try it. And the alternatives aren't suiteable for me.
1) No friend who will buy it
2) Renting isn't my thing (nor do i intend to do it now)
So with that said, only alternative is wait til game reaches half price or something.
Where did I say you had to buy the game to try it?
And that renting isn't your thing is your own problem though.
