I was watching Shrek 2 on the flight (see it - it's good), specifically the action sequence at the end (with Shrek storming the castle while the Fairy Godmother sings "I need a hero"), and I noticed how tense it was; the music synced with the action, the continuous movement and quick-combo moves... and I wondered how that could be achieved in a game. In general you can't create such an atmosphere because you don't know what the player's going to do - you could start the song and the player could spend the next five minutes running into a wall.
Then I realised that actually, it's already been done - though not for a while (and with good reason, I suspect). A genre of game known as "Interactive Cartoon." Dragon Quest, Space Ace, Braindead 13... all games in which the player hits buttons at the right time to influence the outcome of the movie being played out. Does the character turn left or right? Does he jump in time to avoid having his toes chewed off by rabid chihauhaus? It all depends on whether the player press the correct key in time.
There was only one problem with those old games: they're crap. Visually very nice for their time, yes - a very Don Bluth / Disney feel to the animation - but gameplay wise? The player has to figure out which button to press, and then press it at the correct time. Frequently, finding the correct button is trial and error - you get arrow keys plus an 'action' button, and there's no indication of what that action button will do, plus often no indication of which directions are viable and which not. The timing requirement is absolutely criminal, though - the window is usually less than half a second, and is usually in such a place that it's not intuitive.
Take the first screen of Dragon Quest, for example. Your avatar, Lance, must cross a wooden bridge into the castle. When he attempts to do so, a tentacle creature reaches out of the moat and knocks him off. You have to hit the 'action' button to cause Lance to draw his sword and knock the creature back - but you have to hit the button before the creature has even come out of the water. If you miss that window, there's no visual feedback, not even a sound, as I remember... it just ignores the button press.
I think it's a genre worth revisiting, which is what I will do here later because my brother wants to use his laptop. Ciao.
