Instead of just asking questions why not say what you think then you can have an actual conversation instead of such a one way street.
Clearly I'm no expert but I can say what I think. The first game to become a TV programme was Pacman, so what made that different?
Previous games had some threat, aliens, asteroids space invaders, but nothing with any character. Any films inspired by asteroids focused on the people dealing with the menace not the asteroids themselves.
It's the same with Space Invaders or any of the other alien games, they may have looked a bit different, but they were just the nameless bug eyed monsters from 1950s B movies.
Pacman was different, he had a personality, a big smile and a huge appetite and you asked questions about the whys and hows.
There's no back story to asteroids you're in an asteroid field, or space invaders, there's a invasion. The situations are straightforward.
Not so with Pacman, why is he in a castle, why are there ghosts, why does he need to eat all the time?
Unlike asteroids or space invaders you're asking how this event came about, what the back story is.
That is just my opinion, whatdo you think?
