Sales data from December 29th 1997 to December 27th 1999

On most of the internet, you'll find that the best selling game in 1998 is usually regarded as Pokémon Red / Green / Blue / Yellow with 3.006.067 units sold, however sales of Yellow aren't to be combined with sales of the other SKUs as it's done here, due to the way the year numbers for Yellow and for Red / Green / Blue were obtained there is a ±20k error for both games, the ranking shouldn't be altered by the error though.
