T2k & GT:IW
I didn't think it would work as well as it did.
I seem to have successfully combined Twilight 2000 and Interstellar Wars into a fairly successful campaign.
Fighting against the Evil Vilani Empire in the name of the Heroic Peoples of Earth. Various new technologies to be used; deep dark secrets to be uncovered.
According to my players, its just futuristic to be interesting and violent enough to be fun.
I don't suppose theres any chance something like this could be an outgrowth of the T2k timeline? Probably not. T2320 seems to have that timeline pretty well wrapped up.
How do you defeat a culture whose motto begins with the phrase: 'Oh Yeah?'
