Darn it Wikipedia, why did you move your search box?

As far as video game minutiae goes, I don't think it quite stacks up to the necessity of having accurate data as, say, the death tolls of a war.

Finding accurate numbers for any older war is also quite difficult, to impossible, but there at least you know that anything will be a guess... they put numbers in anyway though, even if they really are guesses. Are they all accurate though? Almost certainly not. Of course we can't know the exact numbers, of course, so just like here (but, yes, in something more 'important'), you just have to do the best guess you can with the partial information you have.

Sourced data always wins. If they have a page that says one thing, and you come at them with your own original research estimates with nothing to back it up, then yes you lose, good day sir. If you do have sources, and they conflict with other sources, then the "compromise" of saying there is dispute over the numbers and giving both seems very reasonable.

Hah, the "29 million" number was said in a source all right, but in the same line as "14 million Genesises", while other, more believable sources said "20 million Genesises". Sure sounds like an accurate number to me.
