Alternate names: Area of Influence, Sphere of Influence

The first video game about Dominion was released in 1993.
* Can only build within your own sphere of influence (SOI), or can not build on SOI of others.
* Troops are more effective within one's own SOI
* Actions outside of your SOI are far more expensive or inefficient
* Global magic or similar things can be only used within your own SOI.
Commonly SOI is expanded by most or all buildings the player can construct, though some instances may limit its expansion to specific buildings.
