Big Brother is one of my favorites, but I would change the mechanics of the sandbox game to VN with different routes to follow. I think it would be a much better game.
I can't choose which one I like best? But there are some that I'm waiting for when it's going to be really good, like Our Island, My New Memories and AWAM, this last one, we'll never know when something will happen.
I thought it was a different approach than usual, due to the fact that the MC doesn't remember anything and has to develop the relationship with his sister again. I really like that he already has a very different relationship with each character and has to remember that. It's the same...
I'm really looking forward to when My New Memories starts to get good. Several characters to enrich the harem, mother, sisters, daughters, sister-in-law, half-sisters and friends.
Something with incest, very romantic oriented, long and erotic sex scenes, dirt talk and fetishes. No NTR and no sex violence and preferably well written.
Monkey Business are also a great game, have mom, sister, aunt and cousin. Very good animations and dom and sub paths. The render are a little bit pixelated, but i think is pretty good game.
Gates Motel, it's a great VN, it has amazing renderings, but it's been about a year without updates. Oopsy Daisy, Measure My Sperm and Midlife Crisis were also great.
One of the best I've ever played was Good Girl Gone Bad, lots of different routes and lots of fetishes to explore. The only problem is that it doesn't have animated scenes, but it's a very good game.
