Thats actually intresting...

fallout4 intrest = usa > uk > australia > canada > russia

Halo 5 intrest = mexico > australia > usa > guatemala > columbia

....

I wonder what the corrolation between "intrest" + "population size" vs "actual sales" are like.

Like how many Halo 5 sales will happend in maxico?
