Destiny is like an MMO, they hook you in man. Weren't there a bunch of documentaries and shit on WoW and how it was super addicting and shit? Destiny is pretty much the same way. I'd say just try your best to stop playing during the content gap, that way TTK will seem even better if you end up getting it thanks to all that time you spent away, ya know? I need to take a break from this game too honestly... Maybe I'll just finish leveling a few things first though...
