If you like VN stuff like where you make decisions i will recommend:
- My future wife : Here you are young man with a new roommate and depending on your decisions you can keep her or she will fall for her boss or friends (You can have an Harem if you want)
- My summer: same as the one above with a similar trama since they are from the same creator
- Netorare wife misumi
also if you like to play games made on RPG Maker
NTR Knight: a really good game probably one of the best ones on RPG Maker but as it well known you probably already play it
Shirigaru Quest: you are an adverturer and you have 2 female chilhood friends also more characters can be include depending on your actions it might have a different end
A school life with a gal who is kind to otakus : here you have 3 Gals to choose, each one of them have different personalities if you manage to defend them and keep them you will have your happy end
All these games can be found here on f95zone.
