Well, as has already been noted, you can't please everyone. Someone will always be unhappy. I've spent three times the price on video games that I've finished in a week, but the big thing is it's mine. I can replay it again on a harder mode, faster mode, using different strategies.
It seems as if the original poster was upset and wanted someone to blame because of their lack of creativity.
They probably would have been happy if a hand holding guide was produced listing all the possible things you can do with the game. I'm perfectly happy with the game, as I was with the first two. Some will love it, some won't -- C'est la vie.
