Just watched the video. As a trailer, it is pretty dull, and really doesn't create more hype or excite. However, as a gameplay montage, I think this trailer is great.
I loved how they showed us the new characters, and also teased us by not showing us everything about them.
One thing I picked up about Zero Suit Samus is her gun does several different things...at least three. So it is a gun, which probably charges up and stuns, a sword, and what else?
I personally am liking the simplier level structure...yet I do not think they will be as simple as they appear.
Take the Mario Kart level. It is like the F-Zero level's start...but the 3 platforms can be destroyed. This makes for some unique strategy.
I was overall pleased with all the levels shown in the game, and I think we will all be pleasantly surprised to play it...and see each levels depth.
As for showing only one new character, it was disappointing, but I can live with it. I would rather get mini-movies slowly revealing new/old characters than to have one trailer that reveals everything. And remember, we still need hidden characters to unlock that are surprises.
