My newest city, Republik stadt (Republic City), which is currently under construction, is the future site of one of the most expensive real estate developments in Tirnlander history. The Tirnlander Simlympic Park will be located on Insel von Sport, (Island of Sports) and will be home to the arenas, stadiums, and centers for the finals of the Simlympic Games. The mainland will feature venues for the qualifiers as well as lesser-watched sports, and/or sports whose venues aren't suitable to be placed on an island. (BMX, Street Cycles, etc.)
Here is a quick snapshot. I will post a more detailed description and picture later.
