 This was further developed by Iain M. Banks in his Culture series, which features about ringworld–size megastructures called Orbitals that orbit a star rather than encircling it entirely (actual "Rings" and Dyson "Spheres" are also mentioned but are much rarer).Alastair Reynolds also uses ringworlds in his 2008 novel "House of Suns".The Ringworld-like namesake of the "Halo" video game series is the eponymous Halo megastructure/superweapon.
