Forge Island sadly never saw much use, but a lot of that probably stemmed from the "too little, too late" nature of people's relationship with Halo 4. Don't think that matters much, since it just seemed huge for the sake of being huge. You simply couldn't make use of that space, possible modding aside...

The new Forge maps may seem smaller, but really, without the distinct landmasses of something like Forge World, you don't need all that space. Skyward and Nebula are essentially just a skybox, so there's no real need for building on a particular set of World Units, and yet it's still needlessly larger than Forge World, though that does open up a lot of possibilities (such as isolating battles without having to enclose combatants, or setting up a large number of machinima scenes without having to load a bunch of different maps).

The palette may be a tad disappointing, but the maps themselves are not.
