in literature we use the term motif to describe what you're talking about.

For example, Steampunk is a motif of Cyberpunk which is a sub-genre of the Science Fiction genre.

In a similar vein, you could describe Baldur's Gate (1/2/ToB) as sprite-based isometric (motif) computer (sub-genre) role-playing games (genre). You could add a format, such as RTwP or TB to that description as well, just like you could add "novel" or "short story" format to the literary example above.

"Baldur's Gate is a sprite-based isometric real-time with pause computer role-playing game."

"Baldur's Gate 3 is a third-person turn-based computer role-playing game."

"Dragon Age: Inquisition is a third-person action-oriented console role-playing game."
