That’s generally how I follow it also. Though I add the stipulation that they’re enjoyable hours, and it’s not hardline. I know not every game can be measured that way. If it’s a particular genre or series, l might take the dive anyway. For indies, it goes even further than that. Some I track for years before release, so I pre-order as soon as it becomes available, just to support as much as I can. So $/hr is a good baseline, but it’s deeper than that.
