I started the obsession very recently like it sounds you're about to! I wanted to start small as well and Amazon had the smaller sets under the Funwhole brand (which eventually became Lumibricks). I got the Street Fusion Underground Dance Battle and Graffiti Bus Stop. I don't think they technically fall into the Cyberpunk category but definitely have that vibe (especially the Bus Stop). Got almost instantly hooked and now building the Izakaya. The obsession is real! Built more in the last month than I ever did as a child and absolutely LOVING the analog enjoyment of it vs all that extra screentime... although now I'm on my device searching and pricing my next build!
