Risk Game:
Play Tier: Not really sure. Anybody, but high level teams have a huge advantage.
Parent: Keon
Duration: Very Long
Density: Medium
Number of Ships Needed: 2-4, as organized on a per-match basis
Flexibility: High - teams are allowed to hire "mercs", form treaties and alliances (including having players play for other teams, and scramble loadouts.)
Details: Teams play a standard game of Risk, the turn-based strategy game, on a map based on the GOI world. Clan leaders make decisions via forum post and PM, and the OP is updated with an updating image of the game board. Clans/teams receive reinforcements based on territory controlled, and can be deployed normally, like Risk. The difference comes in attacking/defending. The attacking team and defending team must organize a game of GOI to decide the battle's fate. For example, if Ducks attack Cake, and ducks have 5 ships in Paratius attacking Kian, who is defending with 3 ships, the two will go into a battle. As soon as the ducks get 3 kills, or the cakes get 5 kills, the match is over, and scores reported to the threadmaster. Say the ducks win 3-4. (That's still a win, even though cake killed more ships. Strength of numbers prevails.) That means that they capture the territory, as they killed all three airships above Kian, but they have lost 4 airships, leaving only 1 to occupy Kian. Cake and all the other clans can attack at the same time, etc.
Sorry to interrupt the other discussion, I'd love to see a football-esque league in GOI.
