The equation really should be a bit more complex than (money)/time = value. By that same logic the best movies are the longest ones, the best ride at the theme park would be the one with the longest line, etc. For my self I play because I got rid of the 360 for the Xbone and this is the only title I own currently, but I can't honestly say I enjoy mindlessly grinding the same patrols or running the same circle farming materials for hours. I don't enjoy the frustration of frequent DC issues, not getting credit for soloed open events because at the same moment the credit would be rewarded I'm kicked out to orbit, Literaly hours spent trying to find or build a party for VoG because there is no way to do so in game. Feeling forced to sit through brutally unenjoyable crucible rounds as the only way to obtain items one would think would increase ones DPS. Now there are aspects I enjoy that cause me to endure ALL of the above, When you finally DO get a good fireteam and complete a tough run, finally getting that exotic or purple drop, maxing the upgrades on gear or subclasses, etc. This type of game pushes you to spend a ton of time on things you don't necessarily enjoy to hit the moments when you do. So the real equation should be more like. (money/time)*overall satisfaction = value
