I know the ME system is monsterous in terms of potential storage.  I guess the automation parts were from the other mods.

There are some terrain generation mods that just use vanilla blocks, but varies the terrains enough to make things interesting but not too drastic. 

Last time I used Biomes OP, I was kind of overwhelmed with how much it, though I guess most were cosmetic things with all the new blocks (outside of the biomes themselves).  The only other "add a new biome" mod I've used was Twilight Forest.......assuming you count a whole added realm (with it's own biomes) as a biome.

AE can pretty much autocraft anything you want once you have enough infrastructure. But it's main draw is storing and sorting all your things in three blocks. Since mods very rapidly put you at hundreds of pages of items in NEI, AE is an absolutely massive timesaver once you get started.

I do like Twilight Forest, except that it could be really, really buggy, especially in conjunction with other mods.

Biomes really doesn't add that much since it really is mostly aesthetic, It's just that more biomes mostly just makes it harder to find the biomes I need for resources.

Reason #1 why I didn't even look into Twilight Forest (along with the fact that the huge trees and stuff lagged my laptop all to hell and back.......when it was three years newer than it is now).
