Maybe there are some good games of these but I haven't seem the yet (I'm listening for recommendations if anyone has them). These are my suggestions.
The Loud House:
It's super popular, it's not cover yet (there is a project apparently but they didn't talked for a while), lots of girls, every girl already has a unique personality, lots of incest, house settings are the easiest imo. The bad idea of this one is that 11 girls is a lot fo work to cover and some fans could get upset when their favorite girl isn't updates for a while.
Kim Possible:
I think this show was the first time every straight boy noticed how sexy and fuckeable the toon girls were, even if the audience had less than 10. The girls are super sexy (Kim, Shago, Monic, Kim's mother, Ron's mother, some of the popular girls and I'm probably forgetting someone), school settings are always good. I think this would be great if it's played as Ron because you would have incest (Ron's mother), romance (Kim), corruption (is stealing Kim's mother from her husband classified as corruption? I guess it depens of the way you do it), the school's clown/loser fucking the popular girl is always appreacited. This one is my strongest bet.
Pokemon:
This one has been covered but I think there is a lot of room for this one anyway. Pokemon never tried to appeal to the sexy side for fan service but that didn't stop them from being one of the bigger waifu generators of all times. I'm not gonna even name them this time but in the last two generations you have a lot and lots of variety of girls to work. It can be a dating sim without any battle system and just mentioning the pokemons if you don't want to dig on that, but must importantly, please let me date Marnie
Total Drama Island:
I think people has been sleeping on this one for a while. You have Bridgette, Courtney, Zoey, Gwen, Lindsay, Leshawna, Beth and I'm probably missing someone. People in an island is kinda easy to write and make humor about it. I think this game should have a strong humor sense.
Phineas & Ferb:
I think this one is worth a shot. I think all the girls here are super easy to lewd. Not sure if it should be played as Phineas or Ferb (or maybe both) but you have the elder sister Candace, the chilhood super cute friend Isabella, Stacy (Candace's best friend) and her mom who is a milf, the mother Linda, Vanessa (Doofenshmirtz´s daughter). Phineas & Ferb ability to do almost anything could be really good to create funny situations. Doofenshmirtz´s sad but funny stories are good too.
