Video games from the 8-bit and 16-bit era mixed with real life environments look awesome, and it's a technique that lets anyone's creativity shine. It's something that Kotaku has covered before, but it would be a mistake to not share the new ones.
These superb photo edits are the recent work of acefecoo on deviantART. They mostly feature NES and SNES classics with some exceptions like Day of the Tentacle or Pokémon. My personal favourite is the Earthbound image showing Ness & Co getting into the swampy parts of the world.
