Perhaps, but his taciturn personality is quite iconic and could be quite interesting in the diplomacy screen, having him give dry, terse responses. He certainly accomplished more than TR did, and where TR said we should kill all the Native Americans Coolidge made them citizens and worked to restore their tribal lands. I think TR is a very mixed bag: his work to establish national parks was admirable and his colorful reputation makes him memorable, but aside from national parks it's hard to say he really accomplished much that was positive in his presidency, basically continuing the trend towards expanding the power of the executive branch that was begun by Lincoln. There are plenty of presidents who would make much better great leaders than TR; I suggested Coolidge largely because he was from a similar era as TR and because he was probably one of the better early 20th century presidents.
Eh...don't buy too much into the TR-bashing that seems to be popular these days. TR didn't really suggest the U.S. should "kill" Native Americans; rather, he exhibited pretty much the prevailing Social Darwinist viewpoints of his time in that natives weren't as 'fit' as the "white man" to inhabit the West and should so be 'pushed aside' for civilization (and, really, he was more of the opinion that natives weren't inherently 'inferior', but just needed to be 'helped to become civilized' - sounds racist today but was somewhat radically forward-thinking in that time.) His policies tended to fit more of this view, and though hardly egalitarian were way less genocidal than some (i.e., Jackson).
In regards whether it was good or bad he strengthened the executive branch, that's a charged political discussion (and so this really isn't the right place to hold it); likewise, though I can certainly see where some people might consider his foreign policy bad, I personally would say getting the Panama Canal underway (even if the Colombians had their sovereignty trod on), securing the Philippines, and launching the Great White Fleet weren't the worst things we've ever done in that regards. At the same time, though I think even Harding would be a better leader than Coolidge (despite Teapot Dome, he did a lot to dismantle Wilson's active segregationary policies as one positive), I can see where others might like Coolidge's economic policies, for instance.
So I think we'll need to agree to disagree on this one, though in passing I'll mention I do like the idea of Silent Cal having one- and two-word responses on his leaderscreen.
I think among the broader public, TR is actually still pretty popular.
People who are into politics and partisans for some viewpoint or another have their reasons to hate him. That doesn't reflect popular opinion.
This sums it up brilliantly. A lot of the points raised against (and, I'll admit it, in favor of) TR in this discussion and those in the larger historical community fall into this partisan "TR is good because [reason that matches my political views] but bad because [reason that goes against my political views]" trap. Those who dislike one or the other of those trends are biased against him and so condemn him for doing the thing(s) they dislike (I happen to be the odd case that likes both TR's imperialist endeavors and his social projects, so I'm biased in favor of him in a different way.) However, this inherent disagreement doesn't make him more or less fit to be a leader in Civ VI, where really it should be more importance in history and general notability/awareness that are the deciding factors (where the fact that popular opinion is for him works in his favor).
You know in some of the articles Ed Beach mentions that "if a leader has an Agenda of Manifest Destiny..", does anyone know what era that relates to? Could it fit Teddy Roosevelt?
That's a general mid-to-late 19th-century U.S. term, and could well fit TR, though the first thing that popped into my mind was actually James K. Polk (who, let's face it, would have his own leaderscreen music courtesy of They Might Be Giants...)
