Sorry, your reasoning is not akin to reason. If you buy a toaster that was advertised to have features that are not in the end product you take it back or negotiate a discount. In services like a game it's more difficult because there are factors which might change the outcome. In Destiny for example story and freeroam with somewhat intelligent opponents have been cut. It's not what I thought the game would be according to trailers and show demos. Things change in game development because of many reasons but I think it's deceitful not to communicate fundamental changes. Like a lot of games the lack of solid titles for next gen give the creators a false feeling of success or maybe think of taking the easier road to profit. I can't remember another title to get so many commentsand suggestions about the core of the game. This in itself tells a lot. Maybe Destiny 2 will deliver but I won't be pre-ordering.
