So, if you obviously watched the Halo 4 Panel you would know that Forge is confirmed and will be a feature in Halo 4.
So, what would you like to see in Forge 3.0?
-More things to build with
-Flat land
-Abillity to change terrain (Grass to Dirt)
-Change Weather
-Water blocks
-More forge worlds, or atleast a bigger one
Thats about it for me, might add more.
So what do you expect?

Well there is a “Forge” section in the forums 
I expect it to be more advanced than the Reach Forge.

Ah, right. My bad. To late for that now.
I hope the worlds are HUGE. In Forge World you could see mountians and caves you couldn’t go to, in Halo 4 you could, and you could change weather and add stuff like trees and hills and stuff like that.
I want to be able to change the texture of all structural objects: Pure glass, pure sand, pure metal, ice, grass, rock, dirt, forerunner metal (Reach style), forerunner sand (Halo 3 sandbox style). I would also like to be able to change the background of the map and if not that then multiple forge worlds. Also a weather changer: specific weather with a percentage gauge to control how strong it is, (Ex: Rain 5%=light drizzle, rain 90%= IT’S RAINING SIDEWAYS!!!), snow, hail, clouds, and my personal favorite, covenant glassing apocalypse ash falling out of sky. I would also like to be able to choose the placement of forge world’s sun, so you can choose sunrise, early morning, morning, noon, afternoon, late afternoon, dusk, evening, and midnight. And at night you would see whole galaxies and stars above overhead, maybe even spot a few human and alien cruisers duking it out overhead.
We are still limited by the amount of memory in the xbox 360 console. I hope Halo 5 launches when new hardware is available so true innovative features can be added to Forge mode.
I want an entire disc devoted to a Halo 4 map editor.
