Within each, there are small areas where you can create maps. That way there is variety in location.
instead of 4 cool spots on all of Forge worlds for Reach, there will be 4-5 cool spots in each of the 3 Forge World Areas. Plus the other areas which we don't realize are awesome right away until somebody creates an awesome map there.
How big are the multiple Forge environments compared to Forge World? - bellz1996
The environments will be large enough to accommodate just about any design you can think of, from a Lockout remake to a sprawling racetrack. There will be rolling hills, flat, sterile spaces, big, flat indoor areas and everything in between. The difference is that we’ll use more than one environment – an aesthetic – rather than a giant contiguous space like Forge World. There will also be HUGE FLAT JUMBO Coliseum “walls” that you can instantly place as enormous floor tiles (or walls). All the spaces are being designed with flexibility and performance in mind. The inclusion of a new lighting engine and some unique palettes will make things look more varied and connected. Some simple examples – you can make Lockout and The Pit with relative ease and plenty of room. If you want to do something giant and meandering, you’ll have to incorporate some of the environments existing features (hills, cliffs etc).
