In my opinion, it's complete madness to buy a game before you play it. You're taking a risk if you're buying a game based on theme and looks alone. Only gameplay matters. You can fool yourself that the code will improve, but how long are you willing to wait, while your new toy takes up valuable space in your gameroom?
It doesn't surprise me to see HWN appearing in the market place....a red hot title cooling down with each passing day.
But I understand the compulsion some people have...like that annoying brat in Willy Wonka - "I want it NOW!".
