    contains(f, "Half-Life", 'halflife.png:', ''),
    contains(f, "Mass Effect Trilogy|Mass Effect: Andromeda", 'masseffect.png:', ''),
    (at least a dozen more like this)...
    contains(f, "^(2001: A Space Odyssey|Alien|Short Circuit)$", 'Film.png:', ''),
   )

I just combine the miscellaneous one into generic film/book/videogame icons. Since it's a stored template both the column icons and emblems get updated.

Since I want to display all the relevant icons, I'm not sure that an if statement would work too well. But would list_contains be appropriate?

Yes, given the above you want list_contains(), not contains().

In this context the if is the same as a function call. Both are expressions that return a value. You can have as many as you want, and you can intermix them. In other words, this works:

program:
	f = $tags;
	strcat(
		if '^Fallout$' in f then 'fallout.png:' fi,
		list_contains(f, ',', '^Half-Life$', 'halflife.png:', ''),
		if "^(Mass Effect Trilogy|Mass Effect: Andromeda)$" in f then 'masseffect.png:' fi
	)

The 'if' is slightly faster because it is directly executed by the formatter. list_contains() is a template function call that is not inlined.
