Triad Game Studios would like to make your acquaintance. The studio is working on bringing the spirit of classic RPGs back to MMOs with its upcoming sandbox Dark Relic.
Dark Relic is based on a Dungeons and Dragons campaign called The 6th Aspect from the early 1990s. The developers liken the project to Choose Your Own Adventure books where players can pick the path that interests them the most. Crafting is given a strong emphasis for players who would rather stay at home and tinker instead of venturing out into the world.
The project is still on the fourth stage of 12 planned prior to launch. There are currently four classes and four races planned. Dark Relic: Prelude will be the first of a proposed series set in the game universe.
