In the newer form of Mission Risk (link), where each player has 4 mission cards of varying difficulty, there are a number of ambiguities that are not covered by the manual. After an exhausting (if not exhaustive) search of the intertubes for an official stance on mission objectives (particularly relationships between similar missions), I have landed here to seek advice.
This is when different mission cards can be fulfilled (in part or in full) from actions taken to complete other missions.
This was brought to a head in my last game, where I had the following 3 missions: "Conquer 4 territories", "Conquer 1 territory on 4 continents" and "Take 1 territory from each opponent". Do these objectives need to be completed independently, or can a single conquest count towards each mission?
I was tempted to say that they were, but, in another recent game, I had "Control 2 continents" and "Control 3 continents". If treated the same as the first example, that's nearly the entire map and therefore way more difficult than almost every other mission.
Update (2012-01-30): Using the 3 Mission Cards from the first paragraph, let us say that in my opening turn I manage to conquer 4 territories on different continents, all owned by different players. This fulfils the objectives of each Mission Card. Am I entitled play all 3 Mission Cards over the next 3 turns?
Is there a distinction between the two types of mission other than their relative difficulty, and if that is the only distinction then how is the line drawn?
Also in a recent game, I had the mission "Gain 18 reinforcements this turn" (played after gaining reinforcements). I gamely attempted to suggest it might be possible to play this mission after eliminating another player and playing the captured territory cards for further reinforcements.
My argument went that it satisfied both criteria of being "after gaining reinforcements" and occurring within "this turn" as specified by the mission description.
Nobody else agreed and I accepted that it was a stretch, but I'm keen to hear thoughts.
Somebody other than me tried to claim that a player eliminated that turn (by them) should count for the purposes of the "Have twice as many territories as any 1 enemy". This was swiftly rebuffed. Edit: We assume an implied equal-to-or-greater-than for all quantity-based missions, so the mission in question would, for practical purposes, read "Have at least twice as many...".
In short, any general rule or standard that could be consistently applied to any combination of overlapping/ambiguous mission combinations would be greatly appreciated.
