Sales don't indicate quality very well either though, sure there is some connection to sales and quality but it's a pretty weak connection and hard to recongize, pretty much the only sales trend thats a good indicator it's how well it is, is how it sells months/years after it's been released compared to how it sold when it was released 

I own and have played Demon's Souls and Valkyria Chronicle

By claiming that what the majority likes is bad, you're claiming that a minority knows quality better than the majority. It's easy to say that.

Problem is, every minority thinks they know better than the majority. The majority is really just a huge group of minorities thinking all the other minorities are wrong.

Sure, you can point to dozens of times where the minority was right. Problem is, every single time one minority was right, a dozen others were wrong.

How can you be so certain that the minority you're in is the one that is correct, and that all the other minorities are wrong?

I agree with this, although IMO if low selling titles were really great, then they would have gotten the advertising budget to match it.  If they don't, it's no one's fault except the publisher or the dev misjudging public appeal and not investing enough to maximize returns.  It is hard to predict expected sales sometimes, but that doesn't excuse them if they have a great opportunity and they miss it.

Then you have some serious delusions about FF13, I tried it at a friends house yesterday, I couldn't even play it, it was too easy, the only deaths were the cheap ones, the game was so linaer and boring, I wouldn't be surprized if it was beatable with your eyes closed 

I'm a survival/horror fan.  I've played games in the Siren, Silent Hill, and Resident Evil franchises.  From best to worst, I would rank these franchises in the order of Siren, Silent Hill, and Resident Evil.  In regards to good sales, it's the exact opposite.  Also, Resident Evil does hardly anything for me.  Are you trying to tell me that I'm suppose to  think that the Resident Evil series is a better series than Siren just because it has sold more?  Are you trying to tell me that I should not be enjoying Siren more just because it sold less that Resident Evil?

Dude, you and I are FIF fans.  With your flawed logic, you're saying that Justin Beiber is better than FIF. Are you a bigger fan of Beiber over FIF.  I'm not (Thank God).

Because I know I'm not an idiot, but this discussion is more philosophical then game related, so I suggest we keep it more on topic

So every game that sells poorly is great?

Your argument is even more flawed than the person you're disagreeing with.  There is no accurate measure for what everyone likes, hell even most reviewers stipulate that a review is a guide not a accurate representation of what you may think about a game.  Sales are an indicator of the quality of a game, just like reviews, play time and just general word of mouth. 

At the very least, marketing, which doesn't always translate to quality of the product.

Oh I disagree with that. You're looking at how good a game is as something objective. It isn't. How good a game is is different to everybody, and it's largely affected by factors that aren't even in the game. A very large part of your enjoyment of a video game is psychological.

If someone expects a game to be brilliant, they usually end up thinking it's a great/brilliant game. In other words, a game that has the qualities you put into a great game (good graphics, gameplay, story, controls, or pretty much the mechanics of the game) isn't necessarily liked more than a game which lacks those abilities, as the poor game is expected to be better by the buyers.

The problem of defining the quality of a game solely by the game itself, and not the outside factors, is that the quality o the game suddenly doesn't represent how much fun the average person has playing it.
