@Merrak: Yeah you're right - I think I might try a two colour font - black outline with a lighter centre?

@AnMal: Heheh yep - I'm still tinkering about with the idea a bit but the Broken Lands in the map are areas of land that were damaged by an apocalyptic war over five centuries ago in the history of this fictional world. The areas are saturated with a plasma energy that can be harnessed to power transportation, weaponry etc ... but ... it also causes wild mutation in the planet's flora and fauna.

I've done some more work on this map (any comments would be appreciated):

1.Added a Neon Glow around some of the continent names to improve readability.
2.Added a grid.
3.Added a scale.
4.Added a border.
5.Added the world name: Undomea.
