That's an interesting way of thinking about it - comparing it to shelf space. In the end, I suppose it really is all about marketing more than anything. Who cares about how many games there are on steam if no one hears about them? We're talking about games that no one even finds through steam's navigation tools itself, only through word of mouth, those are the worst ones. And then like that one person said, always putting Shadowgate on sale because of the sheer number of games diluting the amount gamers are willing to pay, is that really new either? I don't think so. It may just be more obvious. I would say it's a good thing that you can put the game on sale all the time and then seek alternate revenue streams, that wouldn't have been so easy back in retail days.
