I could imagine any mid to big budget new game of the week to always score really high that week true.Honestly doesn't mean much because things get knocked around on that list all the time. If we look at just number of reviews or thread activity it's really not super hot. Overall sales for a certain period of time would be more telling.
But anyway, the premise is just strange as it start by looking at the steam hardware survey, see the top 20 most popular skus are cards that were sold above $200
