Initium is a MMORPG browser-based game made by Redditors. Often touted as one of the best games to play while at work/school. It's like a regular MMORPG but made from photographs, complete with Diablo-like loot, monsters, dungeons, and server-wide events.
If you've ever played a MUD, think of this as a hybrid MMORPG and MUD. A game that can be played casually but also hardcore depending on your playing style. A focus on community with a chat that is front-and-center. Stores in-game are all run by real players, buying and selling loot.
Completely cross-platform. Playable on mobile (Play store), or directly in the browser.
