I am not sure who was that, but for sure quite recently. Somebody said that Widelands has lack of additional rules in comparison with Settlers II game cover: Return to the roots.
I have tried that version of the game, and I have seen dozens of meaningless options. Meaningless to me, because I didn't know the gameplay. But all the additional options were hidden. You had to select "advanced options" to see them. That was acceptable. If you don't know them, you just don't go to "advanced".
But there was lack of predefined options. Widelands is much more complex than root Settlers II, even with additional rules. We have wood gnome, which can be from default "peaceful". And you have "autocrat", which cannot be peaceful. Also there is an "artifacts" which should be (from my perspective) not peaceful as default, but can be peaceful.
So defining all the exceptions is a very complex task, but for sure it will add possibilities and will be very useful to the game!
As I can see, we are adding more and more possibilities (f.e. discussion how long should be waterways), so this mechanism (additional options, some of them predefined according to main win conditions) would be very useful.
