“Art with game tropes” implies that “regular games” aren’t art. Which I disagree with. We may not have gotten Shakespeare yet, but writing was an artistic medium before him just as games are one before its version of him.

And whether a particular piece of software is a game is also not clearly defined. This has been a big argument several time, see the one over Gone Home and walking simulators.

Others later down argue over Minecraft and “a win state, fail state, and scoring systems”. Minecraft did not have any of these for a long time, but it would be unconvincing to say that it only become a game after it gained them.
