Oh, I DO know that there are lots of such people. But thats the problem, my friend. Thats the problem.
People like those drag down the quality of PC games. Crysis was far too short, didnt nearly use its potential and Mass Effect was an extremely dumbed down RPG and very justified called a typical console port. Even the levels and enemies all looked the same and it barely had 1/3 of the duration of KotoR (if you could actually keep playing all the side missions and didnt die of boredom while doing so).

If more people would criticize those points they would actually be fixed. But as along as there are people who swallow everything as shallow as a puddle, as long as it has a Blizzard, Bioware or Crytek tag, it will only get worse.
Its not nostalgia, as so many ignorants try to call it. Its fact that many, many game that are 10 years old have far more content, more challenging gameplay and still the same (if not better) gameplay than modern games.
Thats the sad part. If you look at games like Baldur's Gate and then think about games that were there 10 years before it, you wont come to the conclusion that there were better games.

Here is the two problems with your arguement:

1) Flaws don't mean the game is bad. Every game ever released was flawed, even high and mighty classics like Deus Ex and Baldur's Gate. Everyone wants something different from a game, and you can't please everyone... some people will say Mass Effect is bad because it has too much talking, and then someone else will say it is bad because it has too much shooting.

I agree the side missions were kind of repetitive in ME, and the dungeons all looked the same. Personally I was kind of annoyed the game had only one real city and shipped with no AA support. None of this means the game is BAD though, it just means it wasn't perfect. In the end I and millions of others still loved the game and very much enjoyed playing it, and that doesn't make us stupid or mean we have lower standards.

2) Nostalgia effects all things. PC gamers are mostly old-school gamers who have seen the same genres over the course of 20+ years. They have played a hundred FPSs and RPGs and they have their favorites in their minds everytime they start a new game. Most of the time these memories of a favorite game, like Deus Ex for me for example, are tainted by our rose-colored nostalgia goggles.

Is Mass Effect really more flawed than something like Deus Ex? Is Crysis really a lot worse than something like Shogo or even Farcry? It's debateable of course, but in the end the debate is almost impossible to have because someone will pull Black Isle or Bioware circa Baldur's Gate out of their ass and expect the debate to be considered over because of COURSE those games are better.

It's just a flawed way of thinking about modern games.
