I go with Gameplay... Oh wait, that wasn't an option... WTH??? Graphic's are nice but if there is no gameplay, the game SUCK, Grinding is an example of gameplay which in excess SUCKS, Stories are great but I don't buy a game to watch a movie or read a story. I buy books and got to movies for that. Length depends on replay, if there is little replay then make it long, if there is a great replay value then length doesn't matter as much. Action, well again this is vague and is an example of gameplay. Crayon Physics has action but does that count for what your asking or are you looking for combat action??? Speed??? Is this how fast it runs on a machine? or Are you thinking Causal vs Something more Hard core? So to sum it up, IMHO, If a game has great Gameplay, graphics makes little difference, length is variable, Action and Grinding are not options as much as aspects of gameplay, and well Story is Good but again optional.
