Would be bae if 343 made a forge world. Not a 'world map' like in H4 and and MCC, I mean an actual massive area similar to Halo: Reach
They are, I'm pretty sure it gonna be bigger though. I've seen it, have you played on the map 'Pegasus' or 'Orion'? If you look outside the map you'll see a huge map that's the forge map.
