Initium

Initium is a traditional MUD (Multi User Dungeon) that immerses you in a fantasy world inhabited by other players from all over the world. Like most MUDs, Initium has text-based gameplay.

Initium's gameplay is pretty intuitive for anyone who's played an MUD before, but luckily for everyone else it has a simple tutorial you can access after creating a character. After that, the tutorial is always available and can be accessed at any point during the game.

In Initium you interact with hundreds of characters, both NPCs and other players. You can even challenge other human players to a duel and battle them in real time. The battles are also very simple: just choose an action each round.

Initium is a very interesting online RPG, and although it doesn't have especially good graphics, it can by played anytime and anywhere, both on your android device or on any device with a web browser, such as a PC or console.
