Hackmud is a text-based MMO about risking what you have, trusting who you can, and watching your back. Players can amass wealth through exploration and conquest, upgrade their systems, and write scripts against the game.
Hackmud is currently in development. The front-end client is written in c# using Unity, and the back-end is ruby on rails. Most of the game runs on the server, so a lot of the gameplay can be tested and maintained with unit tests.
In 4 months of active development, this game has come a long way, but still has a ways to go. Biggest challenge so far is onboarding & creating a game world that encourages players to continue learning game concepts.
