So what exactly fo you do in a Twilight game? I notice that while he says there should be a game marketed to the 20-30 females (because let's be honest, what serious or casual gamer would buy this thing? In fact, what sort of functional human being with a rational world view would buy this game?), he doesn't say what the game should be about.
Puzzles don't work because solutions fall into the characters' laps, and most of their 'problems' revolve around how beautiful and immortal they are, an action adventure wouldn't work because the adventure part would consist of walking around a school very slowly and 'Adonisly' staring at underage girls, and the action would happen offscreen in the last minute while your character is unconscious in a corner. RTS doesn't fit, RPG doesn't fit because you're already immortal and invincible and have maximum glitter-potential, FPS wouldn't work and for God's sake not even that ball bouncing Peggle game or Pacman would fit unless it was about trying to bounce your vampiric blue balls into an emotionally dead 17 year old.
Sometimes there are other reasons a game hasn't been made, like no genre fitting, and I feel that in this case defying genre would be an idea right up there with making ET again.
In fact, I wholly support the idea of a Twilight game, because it would be so excrementally boring whatever they made that it might even penetrate the minds of the fangirls that this is not a good series, and it can go die under a pile of shit.
