The comparative metrics I used for this game used other high-profile titles, preferrably established franchises. I also broke out a 2nd tier of comparison with DS games specifically, and found that interestingly enough that the math was roughly equivalent. Though too small of a test group to draw firm conclusions, the preliminaries would seem to indicate that "big name" titles lose sales steam at approximately the same rate as DS titles, and perhaps the metric would be true of games in general. More research to do on that. To your question, the following games were used in phase 1 of the calculations: -Metroid Prime Corruption Wii(this was my "control" game) -Orange Box (360) -Pokemon D/P (DS) -RE4: Wii Edition -Mario Kart DS
Again, I make no claims that this is a perfect formula by any stretch, but it does allow one to roughly quantify the effect of time on a new release, barring unusual conditions such as bundling, shortages, etc.
@chill21genlee, You were downbid because of a nonsensical comment, not because of your assertion. If you would have put your second post into your first post, you would have gotten many upbids. People here respect math. : )
The law of diminishing returns as it relates to new releases. Obviously exluding December due to Christmas, I have calculate the aggregate decline in weekly sales for about 20 of the top selling games of this year. From this I extracted a basic algorithm from which I determined my prediction. It's an imperfect formula, but still one that I have found is relatively accurate and informed when used as an averaging method. My comment was made specifically regarding October sales, not total sales. But basically if you look at how every big name new release does week over week you will see that there is about a 3 week sweet spot, and then sales start to dip exponentially.
P.S. Whoever downbid me, I don't think that's cool. No worries if you disagree with my assertions, but reply and say so rather than punishing my thoughts with a negative bid. Thanks!
