You can't have a letdown when pretty much the only thing that has been put out there about a game is just fragmented teasers.
Nobody knows what the game is yet, nobody has sat down and played it and been allowed to talk about it. Nobody knows how it plays, if at all? What is the progression? What is the challenge? What makes it a game?
You fly around in your x-wing (last I checked it was actually tied to the Starwars Universe) and explore planets scanning things, for what end?. You fly and participate in battles... again, for what end? You get attacked by droids because you scanned things... okay... but that doesn't say anything about how frequent these are, if it is intended as a mechanic to make players constantly move around, if it is intended as a mechanic to just disrupt their exploration of the .0001% of a planet they will actually see, ect.
And they want people to buy into it. Feels less like an attempt to sell an awesome game, and more an attempt to try and cash in on hype because the game is nearing the end of a planned development cycle and has to now answer to investors before the game has any substance to it. And there is something very concerning about a company who continues to hold their cards to their chest, asking you to buy what they're holding on the promise that it will be great (when even companies who have done great things in the past are failing left and right).
Oh, I'm sure it has content... Much like Elite
angerous has content to it... But content alone doesn't make for a compelling and enjoying game.
