Ho very cool idias i like the one of the weather here are the mines:
Choose if it is going to be in desert,space,snowing, or normal.
Choose the weather raining,snowing,day,night etc
Choose the matirial of the blocks or pices stone,brick,wood etc
costumize the blocks size
put your old maps from the Reach forge in the one in halo 4
Make a big planice of werever that you whant: snow,grass,stone,desert. because put buildins in a not planice terrain is hard
Put trees of diferent sizes
Put other tipe of stones
unlimited money
More matirial of scenario like radios, computers etc. like in halo 3 ODST they have more matirial and new boxes. fore the forge world because in other maps you can put more scenario options.
