To be honest, I kind of see where
@fiendcode is coming from. The buzz around the game would make you think it's a smash hit, and it is, but the actual sales since release are closer to ~2.7M then if it's at 5.2M. Still a huge amount, but imagine if every triple A game had 3 years of EA to inflate launch numbers.
It also correlates with the data posted earlier in this thread by
@digi_era
About ~2 million people started new classes, so adding that to the 2.5 million people who bought the game prelaunch, we get a deficit of only a few hundred thousand. In other words about 86% of people started the game, which would make sense.
Still, i would take a glass half full approach. 2.7M is still massive for sales on one platform, for a genre that was considered weak for decades. And it's just going to keep growing. It's already one of the biggest success stories of the year, and legs will continue to be good. It's just, uh, not exactly the high water mark that'd you think considering all the "triple A devs are scared" rheteoric that has been seen online. In that respect, I can see how the hyperbole around it's launch might skew how people see the result.
Also, Baldur's Gate was never that niche. It was a huge release on the PC market in the 90's, and it's sales look small because PC games took forever to mature in terms of sales (basically until Steam). It's hard to compare exactly because PC data was all over the place in the 90's, but the original Doom for example probably sold around 2-2.5 million copies during the 90's including it's shareware version, since sales of the shareware version in the U.S. were at a little over a million, and the Ultimate Doom apparently sold around 780,000 (thought admittedly I can't find the source for this on Wikipedia). This would also make sense given the total number of sales for Doom were given to be 3.5 million
by early 1999 in "all its many versions".
The reason I'm making such an outlandish comparison is that Baldur's Gate as a
series sold 3.5 million copies by 2001, only about two years and a half after being pushed to market. As a PC excusive. And Bioware confirmed that Baldur's Gate 1 sold 2 million units, and that 2 sold 2 million units, and the expansions had pretty good attach rates too of ~600k for BG1's expansion and ~500k for BG2's expansion. The series totalled 5 million units worldwide. Source:

The point is, given the state of the market back in the 90's / early 2000's, I think it's fair to say Baldur's Gate was never that niche. It's just that PC games back then often exerted their influence far beyond raw sales of physical editions. It actually would have been one of the highest selling PC games WW by far at the time.
