So the games with story are going to make sense how, if we don't have cutscenes? A lot of games tend to tell the majority of the story through cut scenes.
Sure blizzard released a cut-scenene compilation, but it was stuff already in the games, so collectors could get it if they wanted to, but it did't suck the story out of your games.
Do it smart if you wanna do it, while i haven't seen it yet, "dantes inferno: an animated epic" is supposedly the games story made into a film, in the style of the the cut-scenes in the game. So they take nothing from the player, but just offers them the chance to buy something extra.
