Super Mario Galaxy 2. Don't get me wrong, the level design, gameplay, music and aesthetic are all great, but it makes absolutely no effort to present itself as something new from the first. The first was of course predictable, but the new setting over-powered it. The second one doesn't have that excuse, so it was literally like playing Galaxy 1 again. This is a shame, as, from a detached perspective, it's a great game, but I can't play it without that dirty feeling that I am having a great time with a game that took zero effort in terms of story. God dammit Nintendo.
