@eniko I suspect the people most likely to be okay with this sales pitch think of it like how games at E3 often used vertical slices that sometimes ran on much beefier PCs than the target consoles.
Like, that latter *can* be useful, but... it's one of the reasons I prefer live demos to recorded demos - you can prove what has been done, and what hasn't, and what can't be done... especially in the context of "In-game footage.".
