The multiplayer portion of the first Civilization game
This is the internet enabled multiplayer version of the first ever Civilization game from Sid Meier. Of course, the original infrastructure that was used to allow the game to be played is no longer, though it is possible still to create the server side yourself, if you're a good programmer, or if you manage to find some of the original server side software. At any rate, whether you can coerce it to be playable or not, CivNet is a nice multiplayer game. It allowed up to 8 players to connect and engage in a skirmish, with the variables set before the game was played. The overall map could be set in dimensions, in number of resources and the way it would look, if it was continental, if it was islands heavy and so on. The game was won by the player that managed to conquer all the other civilizations, or by the player that managed to get at the top of the development ladder first. As non game altering additions, CivNet also included an avatar creation tool, called a king maker, that allowed you to create your own avatar, and also leader boards, to see who was the better player. Anyway, a great multiplayer game for its time, the recipe would come to be updated in later Civilization titles, to the current day ones, that are still enjoyed by a lot of Civ strategists.
