Hey, how about sort of monorail to put onto those new rails? Players could get into the monorail and just travel about the planet with style. It would make skyrails more functional and players could set up monorail stations about planets to 'warp' from plant to planet without warping up to the ship too,too much.
The moving platforms are already kind of monorails. Maybe there could be a faster platform to get around quicker? Also, you can use teleporters to get from planet to planet, you only need your ship to get to a new one.
the thing is that planets only load a chunk at a time as your character nears them. so if you're moving too fast, it ceases to be able to load quickly enough and you get jerky movement and blank sections. you can already see this a bit with a hoverbike. or, if you're falling down a hellevator. so it puts a limit on how fast you can feasably travel. with that in mind, you might as well just build a corridor wide enough for your hoverbike between commonly visited destinations. or place teleporter pads in both locations. or maybe the rails with moving platforms coming in 1.0 could be your answer, but i haven't played nightly to test them so i'm not sure.
