Well I agree.... the Mods will maybe even corrupt the game once an update occurs... I suppose we should wait with mods until Notch has created some mod support.
In other news... I tried a new world with seed name T-nex
the surface is a bit weird... sort of islandy.... or lakey.. however you wish to look at it with some very weird mountain formations. I found a massive cave system that im not done exploring yet... and lots of clay. Meh... but Its pretty annoying cos the surface is so random.
