Hello Blenderheads !
I’d just like to point you to another thread i started in the forum of the open source game “FreeCol” (http://www.freecol.org/):
http://sourceforge.net/forum/forum.php?thread_id=1663870&forum_id=141200
This game is a clone of the game “Colonization” from 1994, which i used to play over and over again for a long time. 
As you can see, FreeCol by now uses hand-drawn 2D graphics, which look a little ugly IMHO. So i started using Blender to create some nice terrain tiles and give that great game a nice look that suits it better and might attract some more gamers to it.
I make use of some of the new features of blender like displacement modifiers and node shaders and also some python scripting. Once i have finished some of the work, i will make my Blender files available to the public. Hope you like it and perhaps you can give me some advice on how to make those things look even better.
