^ I think what that really comes down to is a sense of traditional expectations and psychological completeness, as the home video game purchasing process has for most of its history been about paying once and getting everything that was advertised, even if the overall price was higher (people seem to forget about the effects of inflation) and what was advertised wasn't much. I suppose it's similar to how in sports falling short in a championship match is treated as far worse than not making it to the final round (or even the playoffs) at all, even if merely showing up to the final round already means having done better than all but one other team.
Personally, I think if it's really about getting what you pay for that a game like Tetris shouldn't have had the same price as Super Mario Bros. 3, or that Mirror's Edge should've cost a lot less than, say, Saints Row 2. That's something I like about the modern "casual" market, how I can buy simple downloadable games for only a few dollars instead of said games being priced as equal to a major big-name release (especially through a service like Steam that lets me purchase and install quickly without having to leave the house and use gas to drive). That, along with things like 2K Sports pricing their fully-featured releases significantly lower than sports games of the past, or Valve releasing Team Fortress 2 for free and making money off non-vital addons, are big factors in me believing we're actually getting more for less in today's market rather than the opposite stance everyone else has felt the need to take.
I've worked in the industry before (3 years for Sony, no less) and have witnessed firsthand the realities of pushing for deadlines and features getting dropped along the way, so I know what it's really like to have a game not feel complete. If you think DLC is bad, imagine features not making it into the final release (or future patches) at all!
Sorry if I came on as too harsh in these recent posts; some things just needed to be said and I've been holding back on a lot of opinions this year.
