ludology: games as a system of rules and rewards, games studied as games
narratology: games as through the established analysis of narratives pre-existing before games
narrative in ludology: the rules of the game relate a narrative
cinematic narrative: games should pursue story telling along the lines of other media like film
Marshall McLuhlan vs Kojima
Tetris vs Heavy Rain
Though I find Heavy Rain interesting because it openly says its not exactly a videogame.
I also discussed in the thread the need to legitimize games as art so you don't end up with something like the comics code. I tried to open up talks on social responsibility for the images depicted in games. Why these two things relate. Comics, like games, faced extra scrutiny for being sold to kids. Ended up with a weird set of self enforced censorship. Washington spent hours discussing how gay sidekicks were, etc.
I'm not great at cliff notes. Most of the time I'm fighting people who want games to be toys and be allowed certain exceptionalism from the responsibilities and proving grounds that other forms of media have had to go through.
