Just kidding.
Well, so I trew away, some first "rock" formations. BUT I'm not sure if it's nature-cannon. Why is that? Because if I recall correctly at my Geography's lessons each rock formation was "formed" due different erosive/weathering agents. So rocks in dry regions (deserts, savana, ect) would mostly be pointy, since the wind is the main agent. Rocks in topical regions (rain forrest, these stuff) would be smooth, since the main agent is the water(rainy). Rocks in temperate regions would be a mix betwen these two. And so on. (Cold regions should have something like sea cliffs or big glaciers)
So It's quite complex. Specially the tropical ones, since getting nice looking smooth rocks with low poly without normal maps is quite a challenge.
Here's my first "formation".
Since it was mainly an experiment, I decided to go for "temperate".
(The best thing when making rocks is that they are quite modular, and the UVMapping is easy! - Hmm... just occured to me, I'm using blender's generated box mapping, does the game will need hand made maps? [please say no!!!] )

So, please trow your rock into this discussion and I'm sure the rocks will rock!
