Here's another idea (the advantage of California time, baby!), a little deeper than my other possibility.
The Capital of the Eternal Century is a game of urban montage & psychogeography based on Walter Benjamin's Arcades Project.
Think of it as a barely-recognizable 19th Century Paris experienced by a flâneur (stroller) idlely but voraciously absorbing the dense details of street life and urban transformations while out on his daily walk.
Time limitation: 10 x one hour sessions (character creation + one for each of the city's nine districts.)
components (from package 1):
Glass (the glass roofs of the arcades that signify the rise of modern consumer culture)
Ancient (the buried city of the river, the sewers, history)
Emotion (each district of the metropolis represents a mood; plus emotion dice in resolving events).
Character creation: don't know if each player will have a character or if they will jointly control one person. Maybe use a phrenological map of the mind, with its 35+ characteristics.
Structure of play: So the character(s) stroll though a different district of the city each day, taking an hour-long walk. I don;t know if the coflicts/ stories/ encounters that are the focus of play should be the character observing other people's lives (which requires framing new characters in each hour session) or getting involved. Alternative: one straight nine hour walk from ealry to later in the day, allowing for time modifiers based on light and mood of streets throughout day.
Resolution: roll 2d6, one represents level of success (or something along the positive- negative axis); the other dice shows one of 6 emotions. The narrated outcome must capture both the success/failure and the emotion. (So there can be tragic successes, zealous failures, etc)
Themes from the Source:
each session/ destrict should involve one or more of the subjects (convolutes: collections of quotes and musings) of the Arcades Project, for example:
arcades, sales clerks, fashion, catacombs, demolitions, boredom, eternal return, barricade fighting, iron construction, advertising, collectors, the interior, baudelaire, dreams of the future, theory of progress, prostitution, gambling, mirrors...
