C'mon, you can't say the new forge in Halo 4 is not amazing, but what I can't believe is some of the changes they made. Here's some examples: Number 1 is the Falcon, it was the most loved vehicle, and they removed it! They should more vehicles to forge, like the Falcon, Pelican, Phantom, Searph, and the Hornet. It would be amazing it they added these vehicles, and they should re-create the Forge World from Halo: Reach. If they were to make much larger forge maps, they should add even more vehicles for those specific maps, like the Broadsword, Longsword, Mammoth, Elephant, Cobra, Cyclops II, Vulture, Shotsword. Just think about it...
Another thing is about the gas cans on the back of the Warthog, every Halo fan should know that they run on propane, the cans should be replaced with tanks.
