At first I thought it was "7ramed" and my mind was completing the title, however egregious, and then I realized it was "7Framed" and I can't tell if that's better or worse.
Anyway, imagine you are a waiter, working like any other day, and you're beckoned up to deliver room service. Did that work? Okay, now imagine lending me $20. Go on. No? Fine. Anyway, the guy you went to deliver food to is dead. Good job, idiot. And you're going down for the murder. It's a less ambiguous, less stressful Indigo Prophecy, given that the big reveal seems to happen in a non-playable scene.
7Framed "puts you in the role of not one but seven citizens" that are all being framed. There's some tangled conspiracy madness going on that each of the seven planned episodes is meant to clue you in on. I think the stressed plausibility of this world is a hell of a stretch, but it could always make for some fun fiction.
I think the problem with Seven Framedi, just from this first trailer, is this. Sure, Waiter McGee didn't kill that guy. But he runs away and kills a bunch of other guys. So he's still a murderer anyway. Good job proving your innocence. The "online mode in which you frame other players" sounds intriguing, though.
