How will you deal with teleportation? *
The trick, we think, is to make travel a part of the adventure too. Sitting on a ship doing nothing isn't fun -- it's downtime at its worst. But what if traveling from one exciting location to the next was challenging and fun in and of itself? If we can manage that in Vanguard, extensive or egregious use of teleportation should not be necessary. That said, some means by which to teleport will be present in some cases. More on this later.

Will travel be meaningful but hopefully not too tedious as well? *
That is our goal, yes. The journey should be fun, not just arriving at the destination. There should be content along the way as well as horses and other means of faster transportation as a character becomes higher level and needs to travel farther distances.

Will you attempt to make distant lands really feel distant? *
Yes, Telon is huge with all different sizes of landmasses. Travel between lands will take some time, but the travel in and of itself should be fun.

How will you deal with mapping, navigation, compasses, and the like? *
There will be a compass as well as a navigation system, but the latter will be largely based on where you've already explored at least once combined with a few other variations we're working out. More on this later.
