Anybody talking about ‘good’ and ‘bad’ design better bring a solid paper. Otherwise, they’re just talking about what they like. Which is fine, but let’s be honest about it.
I think that this branches out into the greater philosophical question of whether or not games count as an art form.
I certainly believe they are, but I also think that, like all art forms, how a given instance can be judged cannot always be judged with the exact same criteria as the next, especially when the mediums are different.
Watercolors and oil painting can for example be judged on a number of common criteria, but also a number of things exclusive to those mediums.
In music, we can't really judge a symphony of Mozart in the same way we judge a Miley Cyrus song, even if some of the jargon overlaps.
In movies, an action film can't be critiqued like its an art house drama.
But, theres also a complicating factor in that what counts as a medium could actually share nearly all the same criteria but still be unable to be judged the same. TV can't be judged like Movies; a Live show can't be judged like a Studio Recording. Physical vs Digital art. Etc etc.
I think Games have all of these issues, and TTRPGs by their nature have considerable capability to develop these sort of "meta" mediums separate from just being a tabletop game, an RPG, or some mix.
An OSR game can't be judged on the same lines as a PBTA game on the same lines as DND and so on.
Whats good design in one game simply isn't going to be universal. I personally think I came up with a rather brilliant way to systamatize Crafting through dice rolls, but I think itd only really work in the context of my moderately crunchy game. Transplanting it into a PBTA game would simply not work.
Doesn't mean its bad design.
