A while ago I wanted to make some vector-based toy games for fun. I surveyed the available options and basically couldn't find any. If an engine supports vector graphics, it wants to rasterize them ASAP. If I asked online, the general answer was, "GPUs are for rasters, it gets rasterized one way or another. So just do that."
I dunno. I'm not that bright. I don't fully understand it all. But I feel like it should be easy to say, "here's some SVG files for my toy 2D game. I expect they'll scale infinitely well when I zoom the viewport" but alas it was such a migraine with PhaserJS/PixiJs, Godot, and Unity3D.
I'm excited about any sort of project to get you vector graphics as close to the metal as possible before being rasterized (ideally upon draw to the graphics buffer)
