If it does end up being Forza vs GT5 at Christmas (I know how original)

Oh noez looks like madskillz is one of those higher install base = higher sales people. You need to learn about market saturation which is simply that attach rate decreases a huge amount of the number of sales increase.

If indeed install base = sales games like FFX would not have outsold FFXII since the latter released on a higher install base.

 

 Well, to be fair, it is a great advantage to have a higher install base.

What you really have to look at, is

Competition on platform (in same genre) vs software sold (or just hardware sold if you will).

 

GTA increased in sales throughout the gen, as the installbase increased (more possible buyers) while no other sandbox game really took off (low competition).

 

GT4 sold less than GT3, because GT3 released with little competition, and had little for a long time. GT4 released with a large competition.
