Heres my idea of a perfect forge:
What about map creation system AND forge in a way that lets you set kill barriers edit geometry and theme of the map & a more familiar forge tweak that changes game objectives weapons and Vehicles (only this time we should be able to place ANY weapon or vehicle we want well maybe not the scarab but every vehicle you could drive )and place small map changes such as walls spawn points etc for finishing touches. Also you should be able to edit themes of the map generally changing them to things like human, forerunner, flood(include for Machineimas) covenant or natural dessert rugged or forested etc. And lastly opening closing doors light bridges and trees & plants should be included for details this is my idea.
