Though Travian is a war game, a specific objective is required to be accomplished in order to win a game server and this is to be the first alliance to build a level 100 Wonder of the World. The speed server is the quickest one to accomplish this goal.
For some of the principles and details of capturing a plan and building the biggest World Wonder, see the message from Trav Plyr on http://forum.travian.com/showthread.php?t=83597&page=33. One pertinent extract:
- "To get to level 100, you have to have the warehouse capacity to store 1 million of each resource. To build level 97, you need 1 million capacity of Iron, so you have to have finished your infrastructure. That's why we target greater warehouses."
