I agree, theming should probably not be the solution to your problem. It is an interesting notion though, to be able to see different/additional types of info in a theme.
Apart from filename, what would we like to see?
I for one would like to see some kind of condensed date +dev/publisher tag.
So instead of having three tags (“1983.01.01”, “namco” , “namco” ), I would much prefer: “1983 (Namco)”.
