I've played it and Sweden seems fine to me.+15% CS when melee attacking, +10% CS with GG and all's good. Your main fighting force with the GG is quite strong and holds its own, especially once Carebears come out. The GG +10XP/heal still seems to be quite a weird thing but it's a decent sidedish strengthening the other parts. It's definitely a good idea to sometimes check GG progress and if his arrival is very close, recklessly melee attack cities knowing they'll just completely heal during your turn. That's a cool mechanic, though one that's pretty hard to get used to.
