Mmmkey I wanna do a small/simple terrain generator, any tips on how to do this? I guess a voxel engine of some sorts would be easiest eh? Thanks.

nah just go with plain 3d if you want simple, it took me 2 days to make my simple terrain engine, but its very basic
just one texture for the ground and the most simplistic sky you will ever see. Very easy if you use a grayscale bmp as a heightfield. I think voxels are harder to implement
