I agree. When this happens, and it happens a lot (even with films) I get the feeling that I've already played the game and it's not worth it. When they show too much it takes away the excitement of playing. I couldn't agree more with your comment, I keep wondering if this type of trailer actually makes people want to play.
Patient Gamers
A gaming community free from the hype and oversaturation of current releases, catering to gamers who wait at least 12 months after release to play a game. Whether it's price, waiting for bugs/issues to be patched, DLC to be released, don't meet the system requirements, or just haven't had the time to keep up with the latest releases.

I haven't seen the trailer or played the game myself, but what if what you saw was a small fraction of the experience that is attainable? Wouldn't that be amazing?
The trailer still has to have enough to get people interested, and if it's well made with generous amounts of content it should still keep you amazed and interested.
Again, I don't actually know, but it is on my radar and I have heard good things about this game, so I feel inclined towards the positive outlook in this circumstance.
