Well, with Risou, one of the primary things is about the politics, so you can't really get away from it. It's similar to Madan no Ou to Vanadis (the novel, in particular) where it focuses a lot on the strategy of battles and the politics. But the relationship building stuff with the majority of the harem members is actually still pretty darn good. Perhaps this is something you should take a look at?
Other harem series I can think of that is actually good is:
Rokujouma no Shinryakusha (Heroines interactions are great and get a long well with each other. MC is great. Licensed.)
Unlimited Fafnir (MC clearly wants all of the heroines and works for it to keep it that way)
Tate no Yuusha (Clear harem and is story is completed)
Campione (Clear harem and story is completed)
Legion Chronicles (Same author as Campione. Story is completed.)
A Realist’s Kingdom Reform Chronicles (Licensed and is a bit heavy on politics and kingdom development)
Also heard good things about Mushoku Tensei. Unfortunately, the majority lack or don't have great manga adaptations or so far behind.
As for strictly manga stuff, perhaps:
Nectar of Dharani (Clearly harem.)
Kono Shima ni wa Midara de Jaaku na Mono ga Sumu (Actually, this is terrible. But the art is damn delicious. The author, she really should just make more ero doujins, lol)
Rosario to Vampire (Starts out pretty damn bad but by the end, the art and story improves to the point you don't recognize it anymore. Very, very shounen.)
That's all I have as I don't typically read harem manga.
