I have mixed feelings on this. Sweden as it is is a very interesting gaming experience. 25% boost in lumber is huge from a gameplay perspective, simply because now you have a higher incentive to rush build buildings. It's an interesting nation to play as is.
I'm not sure. I think it definitely could be an interesting trait, but then probably as a
leader trait instead of a civ trait. I would like to have the civ traits care about more major aspects of the game to form a main strategy, while the leader traits can be more specialized (expanding upon that main strategy).
And I think that an increase in production and the incentive to hurry buildings is relatively specialized, and as such more suitable for
supporting a main strategy than for being such a strategy on its own. A little bit like the Industrious trait.
The point is, while it is strong enough on its own, it doesn't give the Swedish enough
identity, which to me makes a nation less interesting to play.
Maybe you have a point of it being too imbalanced or ahistorical?
. As per
Nightinggale's higher quality ore analysis, maybe you could also offer
cheaper ore in Europe or a bonus in tools production? Or perhaps, less tools\blades needed to form pioneers, town guards and cuirassiers?
Well, there already are several traits that do similar things. I could make a trait that specifically cares about tools of course, but it would need to be different enough from these other traits, and apart from that, it should focus on a major aspect of the game like the other civ traits, something at least as major as population growth.
Maybe the answer lies in fusing some "production traits" like Administrative and Industrious together to form a civ trait that cares about building stuff (a major aspect), for which you need Hammers and Tools. Although I wouldn't like ditching Agricultural, it's one of the traits I like most.
