Thats a different matter entirely, with FF7 im not on about the sales, the general gaming public as a whole see's it as one of the best games of all time. On the GameFAQs best game of all time in 2009 it came second out of hundreds of games.
Its clearly the more well liked game to the public despite it selling more.
That's fine, but my original argument was with your statement that FF VII was immensely better than it's previous game, which I disagreed with, as do a lot of people, including many reviewers.
Uncharted 3 could technically be worse than Uncharted 2, but sell more due to popularity with the series, or PS3 picking up steam, or due to a variety of other factors. I hope this isn't the case, cause I want UC3 to kick major ass.
I merely disagreed with you on one title, and that's it. If you like FF VII more than VI, that's okay, it's still a good game, and everyone is entitled to their own opinion. I just disagreed with you, and used reviewers as an example to show that quality isn't always the case as far a game sales go.
If you want to go with mainstream popularity exclusively, then obviously the best selling games are the best, because they've sold the most, and that would in deed make them the best to the mainstream, I just see things differently.
