This debate has been going on since the Wii launched almost. Wii Play and Wii Sports are counted as sales. And I doubt there's anything anyone can say to convince ioi not to count them.
And isn't this topic about killzone sales anyway?
I believe Killzone saw the bulk of it's sales when it was added to the Greatest Hits catalogue, and it sold best in Europe. It's plausible it sold at least a million copies, especially with the number of PS2's sold in Europe alone. The only thing is, they didn't make a big fuss about it crossing any milestones in sales, so it doesn't seem readily available.
