Nutaku isn't bad but meh at least, not enuff to deter me from playing since there are no other sites that offer games in a legit way
Games of Desire and Zone Sama whatever - I came from there and paid games before
After seeing Rule 34 used so many times in western games (for some reason, most don't even try to create their own original characters) I had a craving for actual Hentai since "western" hentai, paying on their games has a different system
for DMM games and Nutaku sporting from DMM games, paying usually goes towards premium units that actually help progress the game
for western games, I notice we don't get units. it's just for costumes/skins or more hentai stuff but it doesn't help you progress the game
