It is a little dramatic though don't you think?
If the game isn't good just stop playing or just play whenever you feel like. Why does it have to be playing 10 hours plus a week or posting "im done". It comes across as attention seeking.
And for those that think these I'm quitting posts are necessary feedback to Bungie. They are not. The feedback is simply your play time. Other players don't n3ed to know if you're quitting.
