I'm looking for resources describing art style - setting - gameplay relationship (from game design perspective).
For example, Fallout's colour palette most often is the dark one, models - realistic and not cartoonish. Setting - post nuclear holocaust. Auditory - mature players.
I could also take a different example like Borderlands. Art style is cartoonish, comic but not childish. Setting - vault raiding/monster killing on an alien planet. Auditory - mature players, but still appealing to teenagers (I suppose 13 and up).
Pixar and Nintendo games tend to be both cartoonish and childish. Setting - simple or movie based. Auditory - definitely kids, yet can be entertaining for adults for a limited time.
GTA - cartoonish, comic and somehow childish (especially the first one), yet auditory is definitely mature. Setting - working for crime syndicate/free roaming.
Let's say I create and epic fantasy game (setting). How should I choose most appropriate art style for my game? Are there any canons in art style like there are canons in literature (western, eastern, etc...) How does art style alone suggest what kind of gameplay one should expect? One can release concept art, but setting is generally kept secret so that player could uncover it while playing.
