Well, he gave quite specific example of `sandwich design': "This is your typical cutscene-gameplay-cutescene sandwich." Where cutscenes are arcs as player is to watch them once and actual gameplay is build by looped actions. I haven't played Mass Effect, but I guess this is an example of such design; in all cRPG games gameplay is kind of loop build of schemes like talking to/fighting with NPC, walking around and collecting items.
