It's interesting to me how different games can be.
Dominion barely has any hardcoded interactions at all, which I find immensely impressive, as for the most part, you can just logically deduce how things have to be. On the other hand, theme is without meaning, gameplay-wise.
Another one of my favourite games has dozends of hardcoded interactions. However, it is also immensely thematic, which means you can always just go with what "makes sense".
This isn't really an answer to anything, it just occured to me when thinking about how people approach unclear rules.
