My personal recommendation in descending order:
Translated/ partially translated
1. NTRPG2
2. NTRPG
NTRPG2 side story
all 3 usually come in one packet already translated, they are really good, offer no CG but sprite sex scene, MC is dumbfuck but ntr feeling is really outstanding, for me ntrpg is GOAT for this genre
3. Thug Hero Party (very good with somewhat coherent story, ntr feeling is there and the mc is pretty much useless, multiple ending with revenge route, in short, it's only below ntrpg because it offer no sprite sex scene but the CG is top quality imo)
4. Minako happy life (dumb story, but still good because it offers many CG and no tedious gameplay)
5. married warrior emma (tedious gameplay, still good because it's fully translated)
and all the ntr thing this guy translated
https://www.patreon.com/m1zuki , just go to his mega and you will see his translation (mostly ntr rpg), he is really awesome btw
non-translated
6. kuripick- nanaha yo ( sooooo good, I have bias toward oyakodon tag though... , if translated can be higher than Thug Hero Party)
7. the weakest go the wall ( playing this now, no comment yet)
the translated one in my opinion is really-really good and a good entry for everyone who want to try rpg ntr, nanahayo is very good but you really need to understand moonrune :D
