Nice effort ! Congratulations to the whole team !

And since you wanted to have some "clever suggestions" :
I could imagine a similar thing for Rivellon like I've heard about for Gothic 3 : In Gothic 3, a land has been invaded, and one must free it, regin control, and apart from the factions thing it is (to me, at least) just a game about freeing a land from occupation, slowly, ton by town.
That's something I could imagine for Rivellon as well. Literally travelling from town to town, helping people to free the land from occupation, town after town, as slow as it might be, but with increasing possibilities (for example better flowing markets the more towns are freed + connected together -> transport of wares (simple protecting tasks) and managing through honest and shady people with different intentions. And through woods, of course.

A different thing I thought about yesterday or so was a thing similar to Beyod Divinity : in Beyond Divinity, two persons were working together. Forced together, no matter, why.
I don't know whether this is feasible for the engine, but I could imagine a couple like that - Rhode plus the Dragon Knight, the hero of Divinity 2.
This could imho be interesting, not only, because it would be a "real" (forced ?) couple, but also because this could be an interesting basis for witty remarks. Rhoda, one of the greatest Dragon-hunters, must work together with ... a Dragon Knight ? The kin she was chasing and hunting for so long ?
Plus, I could imagine remarks like in Shakespeare's "Much ado about nothing" (I recomment the movie with/by Kenneth Branagh !).
Just as an idea.
