What I'd like is a drive that works kind of like this:
In atmosphere: drive number is x100 kph
Within N planetary diameters: drive number is kps
In solar system: drive number is AU/hr
Outside solar system: drive number is pc/week
The first two of those speeds might be a little slow.
• A Boeing 747 cruises at 930 km/hr, an SST such as Concorde at 2,180 km/hr. Should a spaceship be much slower? A drive-1 spaceship going straight up will take about an hour to get into space.
• Anything in a circular low-Earth orbit moves at about 7.8 km/sec. Do you want spaceships that can't go into low orbit because they are too slow? Do you want spaceships that are too slow to dock with a satellite? Do you want a setting in which people use old-fashioned rockets to put satellites in orbit because interstellar spacecraft are too slow to do that?
The numbers aren't optimal, but I'm trying to find some compromise of simplicity. It would be better if the increments were smaller (e.g. rating 2 drive is only 15% faster than rating 1), but round numbers are nice for Traveller style play.
How would you feel about making a rating of 5 the lowest in use?
