agreed...the game is good enough to stand on its own so why not show that off?...lots of epic parts in Infinite to put in a nice commercial...that's like a movie trailer showing scenes that aren't in the movie
EDIT: there are actually a lot of movie trailers that show footage that is not in the movie but that's mostly because the footage was edited out later on...with game trailers that is not the case as the trailer for Infinite I saw was airing a few days before the game's release date
thats just intelligent marketing. at hard we are like how come were not doing the things they did in the commercial
but most people probably dont even realize it. they see the commercial, buy the game and dont even notice that they cant do what is displayed.
