Local, what's your favorite Alien design? Is it the classic, just with the eyes perfectly concealed or do you prefer the Aliens look?
AS to doing an Earth War scenario... I just... I don't know. That doesn't sound very appealing to me, honestly.
I'd much prefer a more intimate story with a really good human story. Maybe you could have something like that occurring near the end of the series run... But honestly i'd prefer a series with a very serialized flow that's more about surviving on a space station or something with aliens running amok. Like they're not just contending with the beast itself, but also with the station falling apart and losing power and having to struggle to survive, with lot's of opportunities for surprise deaths, cliff hangars, and additional stakes/drama. Something that plays with the whole "lived in world" more than the movies have had a chance to do.
