Actually a lot of times I only watch the first trailers of games (usually teasers, or cutscene compilations) but never watch any "direct gameplay" or "level" trailers to not ruin it. Did that with Twilight Princess, Super Mario Galaxy, Resident Evil 5, etc. I will do this with Zelda Wii.
But I do agree, if it has Zelda in the name I don't need to watch a lot of trailers to see if it is going to be good. IT'S FREAKING ZELDA haha... the name in itself assures you that you are getting the best of the best. Can't wait for E3 2010.
