Moving back on topic... More info leak! (actually, I was just talking to Hooman and Freeza on IRC)
In Outpost, the starship Conestoga launched from the orbit of Jupiter after having loaded its human cargo.
However, in Outpost 2, the opening animation shows a starship launching from Earth's orbit:
http://www.genesis.outpostuniverse.net/Files/op1-op2_inconsistency.jpgOP2's story definatly takes place from Conestoga's launch because of the two colonies Eden and Plymouth, Plymouth being the 'Rebel' colony.
As various official sources from SIERRA On-Line state (from the mouth of Bruce Balfour, designer of Outpost 1)
Bruce Balfour basically tells the tale of how the governments of the world don't have enough resources or intelligence to build the starships. So a 'Multinational Conglomerate' takes on the task.
The original plan called for four colony ships to be built and to be launced in two pairs. One to one star system, the other pair to another star system (thus improving the chances of survival). Being that this would be extremely expensive and would cause a series strain on the resources of the conglomerate, they scraped that idea in favor of just one starship (named Conestoga in OP2).
<explanation of the inconsistency>Several weeks after Conestoga launched, the plan to break apart the asteroid dubbed 'Vulcan's Hammer' by the media failed. The asteroid was broken into two large chunks both of which would hit Earth destroying human civilization.
Being the only entity on Earth to have working plans for a colony ship, the Conglomerate was asked by the governements of the world to build a second starship. The starship Frontier, fueled by the last remaining resources on Earth, was loaded up and launched just as the asteroid chunks plunged into Earth's Atmosphere. The people of the Frontier looked for the last time as Earth was destroyed knowing that they would never see or feel the comfort of their world again. (oooh... I think I just got my creative writting back! Be prepared, you just might see that in the opening for OP3's novella!)
Anyway, so Frontier was launched just months after Conestoga. I leave it to speculation for everyone to try to figure out what happened to the Frontier. :whistle:
