Dear X,
In troll's game, would he have been better off either picking sweden as a 1 and greenland as a 2
No,
Greenland is better than scandinavia because it controls svalbard. Svalbard is the bottleneck the person who gets scandinavia has to defend if they are to hold the bonus. Being 1 turn closer to it and having no neutrals to fight on the way is an advantage. On the other hand Finland paired with Moscow could give a player a small speed boost. On this map I can't see that working well.
or alternatively greenland as a 1 and sweden as a 3
Yes, a small amount. There are 2 quite unlikely circumstances it can be a benefit:
1)If Boston doesn't pick greenland or scandinavia as his 1,2or3 Troll still gets his multipick and he is more likely to get antarctica. (note this could be a disadvantge in the rare case that troll is hoping to counterpick antarctica or boston is counterpicking it.)
2)If Boston makes a multipick with his 1&2 that doesnt include antarctica and then puts 3Scand, 4Greenland, 5Russia in an attempt to counterpick and then gets first pick he will get scand but not know whether troll is in greenland. Troll will know he is in scand.
Thanks for your questions,
Piggy
