"What Steam does might be teaching the customer that, 'I might not want it in the first month, but if I look at it in four or five months, I'll get one of those weekend sales and I'll buy it at that time at 75 percent off',"
That's exactly what it has trained me to do. I'm being serious about that, nearly every game I've wanted over the past 6 months I've waited for them to go on sale on Steam. Some of them, like Arkham City or Arkham Asylum, I've even purchased twice; first for my 360 and a second time for my PC when they went on sale.(I do alot of transit between the dorms and home and I like having some of my favorites to play on my PC instead of lugging the 360 about 200 miles)
I'll use a recent example though, Kingdoms of Amalur. A friend of mine had been talking it up a few weeks before its release and so I decided that this was a game I wanted to play. Then I saw you, EA, wanted $60 for the digital copy on Steam and decided to wait till it came down to a price point that I, the consumer, felt was acceptable for investing in a new IP. I had to wait like 3 months but eventually it went on sale for 33% off, still not exactly dirt cheap but it was a price I felt acceptable for a digital copy of the game. I didn't just buy the vanilla version either, I bought the complete edition that came with all the DLC which you were charging $80 dollars for before the 33% off. I got the whole shebang for $52 when I probably could have gone to GameStop and bought it used for much less than that.(thus making sure you and the ailing 38 studios got zilch dollars from me)
So yes, EA, Steam has trained me to be a smarter consumer when it comes to investing
my money in entertainment. It has also trained me to instead of buying used, your current boogeyman of doom, when it comes to new IPs that I can instead buy them on sale through Steam when they reach a price point I deem acceptable to my budget.
Of course if you don't like that and try to take it away I can always go back to buying used from GameStop and make sure you never see a god damned dime of my money.
