Nice, I didnt know the stats but it makes sense. I bet now half of the fanboys here are calling you the troll and those stats fake.
He's objectively and conveniently ignoring publicly available data that contradicts his narrative.
From the very page he linked himself:
Baldur's Gate Series
MetaCritic Scores (as of February 2008):
Baldur's Gate: 91%
Baldur's Gate II: Shadows of Amn: 95%
Baldur's Gate II: Throne of Bhaal: 88%
The Baldur's Gate series: Baldur's Gate I, Baldur's Gate: Tales of the Sword Coast, Baldur's Gate II: Shadows of Amn, and Baldur's Gate II: Throne of Bhaal have sold approximately 5 million units world-wide
Baldur's Gate, released in 1998, has sold over 2 million units for PC and has won many industry awards; in 1999, BioWare released Baldur's Gate: Tales of the Sword Coast, a Baldur's Gate expansion pack. It debuted at #1 worldwide and sold over 600,000 units
Baldur's Gate II: Shadows of Amn, was released in Sept. 2000 and continued the award winning story line of the Baldur's Gate series, selling over 2 million units so far; in June 2001 Baldur's Gate II: Throne of Bhaal was released, the expansion pack to the award winning Baldur's Gate II: Shadows of Amn, and the conclusion to the Baldur's Gate series, selling more than 500,000 units
The Baldur's Gate franchise has won multiple Game of the Year and RPG of the Year awards
So let me stress the point: Baldur's Gate II Shadow of Amn sold "over two million so far", where "so far" in context (and even assuming no update since it was wrote) means at least 2008, when that summary was published on Bioware's website.
Meanwhile these are sales data for DOS2 on Steamspy:
Owners: 2,000,000 .. 5,000,000
Which means that it should be anywhere between 2,000,000 and 5,000,000 copies (probably somewhere around 3 million) and we know from the horse's mouth that it was already above a million by November 2017, six weeks after launch.
BG2 was, according to all the source already posted here including Bioware's official site, at 1,5 millions almost two years after launch (se my previous post) and "above 2 millions" seven years later, in 2008, according to Bioware' self reported data.
This means that his claim that "BG2 sold in its first year more than DOS 2 sold in its first year" is complete bullshit. Even taking the worst possible data projection and most conservative numbers about DOS 2, they were at worst on even ground.
Please note that no part of this is meant as a judgement on the quality of either title.
The problem is just that people should not make up convenient shit and then get aggressive when proven wrong.
