Not until content creation tools get smarter. When your level is made of simple tiles in 2D top-down perspective, you can have large levels with lots of sprites, but when each character has to be a fully rigged 3D model and each tree rather than being an 8x8 pixel smudge is instead a fully 3D physical object with leaves that respond realistically to wind... Well, it's hard to make them by hand.
