If you're not familar with ocrtrees (I wasn't), this is a good intro:

They look like a nice way of building voxel landscapes.

Hahaha the title of the article "Let's code ... a MMO" (RPG) is sooooo true, at university people learn programming, drawing the first cube, and right away "hey now we want to do an MMORPG", I say: "You know that there are already tons, all done by huge teams in several years of fulltime work?", they say "Yeah, but ours will be better" :D

@jaderamiso: Octrees are like quadtrees, in 3D. You maybe first want to understand Quadtrees (very very useful), just google it and the first 2-3 results are great. Then replace the word "square" by "cube" and you got octrees.

Both Cube2:Sauerbraten and Red Eclipse (which is a Total Conversion of Cube2) FPS engine are Octree based so i think they are good places to look for working code if you learn better that way.
