Yeah...it's the "it" game right now. Why sell for anything less if people are going to buy it at full price?
If you're a true Cheap Ass Gamer, learn to play "behind the curve." I know it, I just can't follow it. It's all about patience. There are always good games to play. Question is, do you want to follow the hype and masses and pay $50 for them, or do you want to be a year behind everyone else and buy them for dirt cheap?
Case in point: San Andreas. That's was an "it" game. You had to have it. Wait a few months, thousands of anxious gamers waiting to get the next "omg u have to have it game" plop their copy of San Andreas up on eBay...the supply outweighs the demand, and you can get it for much cheaper.
Seriously. If you want it cheap, then just wait. Like I said...there are tons and tons of games to play, many just as good as God of War, yet for a fraction of the cost!
