I've found it very challenging to get started (to be fair, I was trying to start with HeroQuest - it's not complicated rules-wise, but there's a lot of pieces to move around). I think each game maker can make their own choices about how the UI should work so it's not clear what I should be looking for (in terms of UI widgets). Then they need to document how the game UI works which seems to be hit-or-miss depending on who wrote the mod.
For Heroquest, at least, it then seemed like I needed to spend a bunch of effort to get past the 3D aspects of the game in order to focus on the actual gameplay (which is fundamentally 2D).
At the end of the day it feels like trying to smash a 3D peg into a 2D round hole - I love the idea but in practice having a dedicated, 2D board game framework seems like it might be a better fit for board games.
What have you all found?
How did you get started?
How do you find good docs?
Is there a Boardgame Simulator out there that I'm missing? :)
