Re: [Space] Technobabble for my new campaign.
It would take 9.5 years for a 0.1g spacecraft to reach 0.98c (though time dilation would probably fiddle with the numbers).

That's according to someone watching them from a "stationary" point. From someone on the spacecraft, every second is five seconds in stationary space when going .98c.

But .75 C gives you a fair amount of time to respond and protect yourself, especially if you've got FTL. And WWI, which was lost when national economies broke down, would be fought and the resulting civil wars over between launching your weapon and it arriving.

Re: [Space] Technobabble for my new campaign.
Think carefully about whether 0.1g/5% is sufficient for your needs of in-system travel times. It's very possible that it may be found lacking once you try mapping out the timings of individual adventures you plan to throw at the PCs. In which case you may want to consider pseudovelocity as a way to get faster travel without the kinetic kills.

Re: [Space] Technobabble for my new campaign.
A Star Trek The Next Generation RPG system (form Last Unicorn Games) had a table on which you could roll and it would give you some random technobabble (in case you're out of ideas to make something up when the PCs have done something unexpected again).

So it comes down to how long it takes a ship to get to "flat space"...100 planetary radii is 400,000 miles for the earth...not too long even at 0.1 g if you don't worry about slowing down when you get there. |

Also, do consider the troubles of lifting off with a mere 0.1g drive. Works with winged launch, but not with wingless. And you can't meaningfully use wings for planets with a trace atmosphere, and your runway requirements will be huge with low thrust/low air density in general. |

As far as take offs, that's already been thought of at length. Campaign is starting on an Arcology farm on a Ceres analog, with 0.03g at the surface. They'll have winged shuttles for most large inhabited planets, when they get there. They don't actually have their own ship yet. Yet. |
