I got bored, so I did this. Those graphs are based on amazon most wanted list of several countrys (USA, Canada, UK, France, Germany and Japan). The amount of point is not going to translate into sales and everybody has to be aware of that.
That said, It may give hints on some kind of "general hype trend" for games/systems.
Now how I do that :
Every day (amazon most wanted list is updated daily, I am looking at systems/games positions in the list in each country. If the game/system is first, it scores 100 points. If it is last (100) it scores 1 point. (if second, 99 points ; if third 98 points and so on...)
The average amount of point on the graph is calculated by the following formula :
(US points x 3 + Japan points x 2 + Canada points + UK points + French points + Germany points) / 9 (I am trying to consider the size of the markets...)
Some arbitrary rules : - A bundle give only point to the system, not the game. - A game or a system can go over 100 if several SKUs.
I started this little game since February 4th 2014. I am tracking the 5 current gen systems as well as several games ( I will give a list later).
I can do weekly, monthly or no update depending on how interested people will be.
So here is the hardware graph from February 4th to now.
