I just remembered a game that is (was?) in development on the tigsource forums. It doesn't seem like the devlog has been updated in months, but the first video posted of it I really enjoyed. Somehow I found its style very evocative and immersive even though it's very simple. Maybe it was the music. Here it is:

It's interesting to compare with these with How Bees Work - I found the style in the video to be much more evocative, though only a few things were different, like the different ground textures and heights and the slight fog effect as objects recede into the distance.
Well, I guess I'm a sort of modernist by saying this, but maybe you should try to find the equivalent of "sketchy" in whichever rendering technique you're using. In general I think we should try and find new forms of beauty in this new medium.
Funny to hear that, coming from someone who hates pixels so much.

But I agree. My approach would not be to use some post-processing effect to mimic the appearance of sketchy painting on top of a polygonal rendering, but to
replace the polygons with something entirely different. Like
this.
I want to try using a probabilistic rendering technique that is not built on triangles, but on networks of connected lines and flows of particles. I just don't know how it would work yet.
