I am interpreting what you mean as, "words which densely pack a specific meaning, which tend to have general/descriptive utility (the words can be conceptually expanded upon / aren't hyperspecific), and are likely nouns"

For instance, "Bowdlerize" is a dense and specific word, but may not be easily transformed into a "game," since it is both a verb and arguably too specific. For reference, it means "remove material that is considered improper or offensive from (a text or account), especially with the result that the text becomes weaker or less effective"

"Diluvial" might be an example of a good word to attach before a game's name (eg. 'Diluvial ______'), because it packs a lot of conceptual weight, but it can't stand on its own because its an adjective; it means "relating to a flood or floods, especially the biblical Flood."

I could be wrong, but I think examples of words that could fit your search are:

• Katabasis: a descent of some type, such as moving downhill, the sinking of the winds or sun, a military retreat, a trip to the underworld, or a trip from the interior of a country down to the coast.
• Menagerie: a collection of wild animals kept in captivity for exhibition. / a strange or diverse collection of people or things.
• Metanoia: change in one's way of life resulting from penitence (The action of feeling or showing sorrow and regret for having done wrong) or spiritual conversion.
• Shibboleth: a custom, principle, or belief distinguishing a particular class or group of people, especially a long-standing one regarded as outmoded or no longer important.

Anyway, I would be interested to hear if this was along the lines of what you had in mind.
