"Boss rush games"??
There's MTX again. I'm going to learn that term!
Reviews didn't even make the top 3 for research!? Oh, there it is on purchase triggers. Huh. I'm not understanding what that's doing in that category.
The slide you reference doesn't make sense to me, either. Very few games will see a higher count than release day. Even No Man's Sky, with all its free DLC over the years, can't buck that trend. I could see the last category being as big as the top two for games that have been around for several years - a trickle of water will eventually fill a bathtub - but the "within a few months" category? Maybe a lot of people are buying games after the hype and before the sales but then leave those games unplayed for a long time??
