Asheron's Call released in 1999 in direct competition with Everquest and Ultima Online. Asheron's Call, although never heralding the same sort of success as the other two games, remains active and well-populated to this day.
Taking a slightly different course than the other two games on the market, the world of Asheron's Call launched full of creatures that were atypical for a fantasy setting. Rather than seeing dwarves and unicorns, players fought insect-like Olthoi, the cat-like humanoid Drudges, and reptilian Sclavus.
Perhaps the most interesting part of Asheron's Call was the idea of limited magic-use. Players could create their own magical spells, and the less used a magical spell was in the world, the more power it could create. It was an interesting and intense system, one that many people enjoyed.
