I just feel a few recipes should be added/changed.
Here's the current known lineup:
Sand ---> Glass
Snow ---> Grass
Grass ---> Dirt
Here's what I feel the updated lineup should be:
Sand ---> Glass
Grass ---> Dirt
Snow ---> Water (This makes more sense)
Dirt ---> Sand (Sand is basically really dry dirt. Sort of. Don't give me that look.)
Concrete Block ---> Road (Think of a cement mixer. First suggested by SnakeZXZ.)
Black Brick ---> Red Brick or Red Brick ---> Black Brick (can't decide if blackening from being charred or being made red from the heat makes more sense. Maybe making them both work would be fine.)
Feel free to add your own opinions and/or revise the list. I'd like to see something get added because of this thread!
