Is It A Game?
Analysis: Bet you thought this would be a game, because Super Mario Bros. is usually a game? Well, you're wrong. This AIN'T no game. Which is a double-negative, meaning this IS a game, technically. But actually, it isn't a game: it's a movie. That's why you're able to watch it in theaters or on your TV and not play it using a videogame console.
Analysis: Hide and seek is a game that children play, but this isn't that - it's just a movie that happens to share the same name! And the film is also not about a game of hide and seek being played, because that would not be cinematic.
Analysis: It's called Ender's Game, but then the tagline is basically saying "Hey, that title is totally wrong. Sorry." Well...that should probably not be the tagline. If you've read Ender's Game, you should know why that should not be the tagline. Pretend you didn't read that tagline.
Analysis: Last time, it was a game? Apparently. Anyone ever seen the prequel to WitchTrap who can confirm whether or not it was just a game? That seems like a bad idea for a movie, just having it be a big game.
Analysis: There was a point in time when Double Dragon was only a game series, but not anymore! Now it is also a movie, in addition to being a game series, which is all it was prior to this. It's also an excuse for Robert Patrick to burn all the goodwill he earned from Terminator 2, but that's unrelated to whether or not it's a game (reminder: it is a game still, but now it's also not just that anymore).
Analysis: It's more than a game...it's the chance of a lifetime. That chance is "to win a game."
Analysis: Since the entire premise of the film is that it isn't a game, but a real interaction with a computer in control of nuclear weapons, it not being a game is very important. If it were a game (as the protagonist believes early on), it would make for a very uninteresting film, where a guy just plays a game.
Analysis: Shoot, nevermind.
