Well, in games, as you say, it is expected. That's part of the base concept. You're the protagonist, the mover of the story. It's part of what interests me in the story. In a TV universe or film that is a little bit different. It can work on the same rules, but there is also a sense of a living, breathing, world. Well, if you create this large world, but then constantly have people knowing everyone else it strains belief to a degree. It can be very effective in a game, but distracting in a film series.
