It's actually not, if you look it says subject to change on that trailer as it does with every game that has yet to be released.

Its not just the trailer its the whole campaign that Bungie did to advertise this game...plus wtf would the "subject to change" even mean for a game trailer....its like a movie trailer with "subject to change" what kind of change? Like we get a different actor/actress to the one shown in the trailer once the film actually releases? There is a reason that the initial reviews for this game were bad.

Subject to change means anything and everything in the trailer could be changed. I don't know if you know what happened at bungie, but here is the gist of it: A few months before the original release date for destiny bungie put a supercut together showing the whole game in one film, basically a quick way for execs to get up to speed with how the game plays. The execs watched and didn't like how it played, so they extended the release date and cut huge elements of the story to work with how the game plays now, now that could have been a poor decision or a great one, we don't know. However that does not show that they cut content to sell it back, they would have had plenty of time to make dlc content over that year and probably already had some done.

Yes i heard that story, nor you or i will be able to say "yeah thats exactly what happened" one thing that did happen tho is people bought the game based on original advertisement, we were never made aware of the rehash until we bought it.

Sure but you can say that about many games, it's not just destiny. 2014-2015 was terrible for games, and don't forget the one that started it all, the worst game to be released in years by Ubisoft, watch dogs. Remember the hype for that?

unfortunately (or i guess fortunately), watchdogs never grabbed my attention so i never got caught in that hype
