This is the meat of it. If someone can pitch a convincing Demo scenario, with character creation included, and keep it undr an hour to 45 mintues in length, we can at least prove it's at least feasible and contained.
Well, of course it could be done... That's not really the point though... It simply isn't a marketing tool that Bethesda uses. Nor do many of the large franchise developers. Rockstar doesn't do demos when they release games like GTA or Red Dead. Has there ever been a Halo or Call of Duty demo (excluding multiplayer maps)? When the hype surrounding a game is a big as it is with these kind of AAA titles, a demo is unnessecary.
