Alien, Stargate and 2000AD had already been done.
(At least twice for stargate. People actually said it wasn't bad back in the days.
2000AD used a MongTrav variant back then. It was Traveller, so you either like it or hate it.
Alien by Leading Edge was called one of the worst TRPG ever... Cause its the Leading Edge system they used. v=3=v )
Would be cool for them to get some new breathes though. (But Wendy's... Well... =_=\ Do we get discounts if we play in there?)
