Massive Chalice on the Xbox One and PC relies heavily on this - I'd say it was like Crusader Kings crossed with XCOM: Enemy Unknown but then I'd just be insulting both games. The premise is as follows: A mysterious threat known as the 'Cadence' is slowly taking over the land. In order to defeat this Cadence, humanity must ensure it has enough Heroes to fight, and to do that, they need to breed the Heroes they have. It's an interesting concept, and the game takes place over a span of five hundred years, but the game fumbles it.
Five hundred years is a lengthy span of time - but the Cadence attack so rarely they're less of a slowly-encroaching world-threat and more of an occasional hiccup in the steady progression of basically nothing. I've had whole generations of Heroes grow old and die without ever meeting the Cadence, and although the game lets you pick between Thematic (serious) or Comic ('funny') names, you're still going to be using the same cartoon character models with shoulder-mounted crossbows or cabers. The melee weapons are cabers. Like battering-rams but...well, exactly like battering rams.
Anyhow - the battles play just like you'd expect, and your Heroes are pretty fragile but level up fast. I think the aim is to breed high-level Heroes to produce high-level offspring, but everything takes so damn long your Heroes get one battle per generation, at most.
I started this post with the intention of recommending you try the game, but then I couldn't think of anything positive beyond it being an interesting concept. Noble houses and eugenics is always weirdly fascinating, but Massive Chalice is not.
