I can see where you are coming from with your argument, but when all is said and done the game was purchased. It should be on the charts as there is a physical copy in someone's possession. If you do not count that, where does it end? Should you not count systems that are given away? How about games that are not very good, do they not count those as well? Just does not make sense to exclude something even on the basis of a forced purchase. I mean if they didn't count forced Windows purchases, including piracy, with computers Microsoft's market share would be about 10%.
