I won't comment on what was promised with marketing, because I never really looked at it. I bought destiny knowing it was a bungie game and have since spent many hundreds of hours playing it. I'll start by saying I agree with you somewhat... BUT I don't think it's possible without either exorbitant amounts of time, or a ridiculous studio size or both. What game has ever achieved this? The closest I can think of is Skyrim, which had a 5 year development with the massive team at bethesda and even then it's been criticised for being static in the sense that nothing ever really changes in the world. Not to even mention that it's only single player, the online component adds a massive extra workload to a project. What I'm saying is in a perfect world that vision would be realised but games take so much man power to create it just isn't feasible to create a game with that much content in a reasonable time frame. I have no doubt Destiny 2 will have more content with a more polished formula (now that a game engine is in place - building one from scratch would have been a huge part of this first game) but people just need manage their expectations.
