When is Tibia's birthday?

Question

Can you please tell me the exact day of the birth of Tibia (when Tibia went online for the first time)

Answer 1

A few students at Germany's University of Regensburg decided to craft their own MMO in 1996, a project that became Tibia when it officially launched on January 7th, 1997. The first non-dev player took a few days to show up, and from then on a slow trickle of adventurers gathered inside the game.
