Factor 5's Pilotwings reboot was an open world game developed exclusively for the Nintendo Wii. The project originated on the Nintendo GameCube, but was eventually pushed onto the wii. Factor 5 experimented with with a kind of head tracking glasses that effected what was displayed in relation to the player's position, giving the illusion of real depth within the display. The game started out with a more serious tone, but gradually became more casual like past Pilotwings games. Factor 5 later made the project its own IP, and developed it under the title Wii Flight, Wii Fly, and ultimately WeFly.
