Meridian 59

Meridian 59 was among the first 3D massively multiplayer online role-playing games. Players create characters, and then advance in power by defeating monsters, completing quests, and collecting treasure.

The alpha test of Meridian went online on December 15, 1995. It was commercially released on September 27, 1996. Several free, downloadable updates were released during the next 18 months: Vale of Sorrow, Revelation, Renaissance, and Dark Auspices. The original servers were shut down in late 2000, however the game continues to be available at its website.

It has a Doom-style first-person graphics engine, with both software and hardware renderers.
