Obsidian Entertainment, lead developers of "Fallout: New Vegas", had a work-in-progress RPG called "Backspace" with time travel, aliens, and space stations. The game was to run on the Skyrim engine and utilize its Radiant AI system, but production was halted in 2011 and the game has been shelved. Obsidian says the game was meant to be a 'Sci-fi Skyrim".br br Source: br Images: Kotaku.
