Improvements
 

Graal Kingdoms needs more life. Maybe less monsters and add in some non-hostile NPCs like Deers and turkeys. More land diversity. Instead of just sand, grass, and snow, maybe mud, deserts (not just sand, but desert, with cactus), and small ponds. Kingdoms has NO ponds ever noticed that? And like other people said, create new monster instead of recoloring them. The sand worms idea was nice I liked that, but instead of having a yellow iguanadon, have a Rock Monster.

True... the should be more life
and also more terrain, i mean:
Dustari= Sand, Grass, Stone
Forest= Sand, Grass, Stone
Samurai= Sand, Grass, Stone
the only difference between the kingdoms is the name!

There are no rivers either...

What?? Last time i checked there was a river west of bomboria. :o

You can't really call that a river... And it's the only one (if it's one).

What different landscape should there be? Okay, Pirates get to have more sand, so does Zormite, and Forest should be, oh wonder, a giant forest, but what about Samurai and Dustari? How would they differ from the standard beach-greenland-forests-mountain-pattern?
I agree that rivers would be nice, or waterways, but they'd be of more use if there were goods which only a boat can carry... smaller board fir river-travelling would be good, too, if necessary at all...
