That's too bad. Smaller blocks are the most interesting way I've considered of putting things into a sort of scale with the ground.
I love the planet explorers method, where you use smaller blocks to make weapons and armor. I would have loved a special creative workbench where you make weapons and equipment, with built in effects, that would be tiny.
It was how i envisioned robots would be made in the game.
Then again, i don't know how many devs there are. If the game takes off, then it might be something that the modders do.
