A121 Sim Cluster
A121 is the temporary name of a Sim Cluster identified at Coordinates 765-777/1083-1105, Grid Sector G10 and H10, Western Ocean. Interesting is the fact that sims in Southern part of the sim cluater are white on map, while sims in North are blue. The reason for that is that sims in South are tropical beach - themed, while sims in North are flooded.
A121 is the only sim cluster where majority of the sims are sublerged.
