This is a Simulation ruleset game! This will be the third official game to use Sim ruleset, this time using v2.99. A lot of bugs and disbalances have been fixed and final checks are underway. This is the first Sim game to be played using Freeciv 2.6 server.
General information and Sim ruleset guide can be found on its official page (*click*). At this moment the official page is 90% complete, but as the game start time approaches, it will approach 100%. Current 100% full description of the ruleset properties can be found in the corresponding Freeciv forum thread, although in a not very orderly presentation. However, there are also plans for some additional upgrades that are not listed in this thread either (because they exist only in admin's head). With all this in mind, even now the official page is an Essential First Read (and will turn into Full Manual by the time the game starts). (Hopefully.)
