I’m not super-familiar with how difficult papercrafting is, but I’m willing to bet that it takes a significant number of hours to build something life-sized. Minidelerium, a Swedish papercraft hobbyist, made this kickass Zelda figure in 126 hours, which is three weeks of working 8-5, Monday through Friday. (She then gave Zelda away, which seems so sad.) Nevertheless, the results are incredible, and if I had room in my house, I’d consider taking up life-sized game figurine papercrafting as a hobby, too.
