I go with handmade styles a lot. Like real world, handcrafted miniature art. It isn't outright unique but it is nonetheless rare, and that means it stands out. I have "miniature multiverse" in development and the initial concept was thinking about games of the Myst/Riven sort and wondering what it might be like if someone physically built entire fantasy worlds with a handcrafted attention to detail.
And so I kind of figured out how to capture 360 degree views inside some sprawling O scale miniature environments and created my own Unity workflow for building a 360 node based puzzle adventure game. Used a 4k action cam and took photos at 15 degree rotation increments for each node, stitched them into 360 Panos, layered animation in and swapped out the sky. Used basic spheres with a double-sided unlit shader. Made heavy use of playmaker.
Then there is a second miniature art project "miniature miniature golf" or "miniatureminigolf" it is a simple isometric mini-golf game but all the graphics, again, assembled in scale miniatures with that particular tactile charming and colorful look.
You can check my profile for more info, I also have game dev asset packs (pbr textures, 3d models) and an etsy shop offering printing services + papercraft kits and such.
