I hope that every Forge World has one default layout (like Foundry and Sandbox) that is featured in matchmaking, so we will have 13 maps at launch. Having many maps on the same Forge World will probably make all of them look bland like Reach’s.
The Ravine looks like it could produce some VERY unique maps, including BTB maps. We haven’t seen the other two environments, so we don’t know. My favourite thing about the new Forge is that we get THREE different pallets (Sets of objects) that AREN’T grey.
This means that we’ll be able to build much better custom games maps, and matchmaking maps that won’t get boring. I don’t expect them to each have their default layouts, but multiple layouts in different areas of each map.
