I play Cyber Nations.
Most of the gameplay in Cyber Nations takes place in Planet Bob (also known as Cyberverse and Digiterra). When a player first creates their nation, the player may choose their nation's name, capital, location, tax rate, religion, government type, team, and DEFCON level, most of which can be changed after their nation's creation. After nation creation, the nation gets a random pair of resources. The player may also set their government's position on issues, establish trades with other nations, and purchase infrastructure, land, technology and improvements. Even though it isn't directly coded into the game, nations may also sell technology to other nations by using the Foreign Aid System. Nations can collect taxes and pay bills every update cycle (when the server hits midnight).
A major part of gameplay is based on player-created alliances. Alliances are built into the game, however most of the alliance's activities occur in off-site forums and IRC channels. Being part of an alliance offers different types of benefits, such as aid, protection from attacks by other nations, advanced knowledge of gameplay and strategies, as well as camaraderie. Although it isn't coded into the game, alliances have the ability to sign treaties with other alliances.
