I have built almost anything coming on plastic sprues. I don't really build ships anymore though, small scale ships generally look too much like toys to me, at least when I make them, my hands are not as steady as they once were. And large scale ships are just too large for me. I have been tempted, some very interesting large scale ship models have been released the last decade or so, as projects they are just too demanding when it comes to time and focus. I had only seen two group builds when I wrote the comment you quoted though
