1. Kichikuou rance: While it has the old feeling right now it is a great game that has the elements that I like, which are:
-Things can go badly, not only because of choices but if you didn't save a character.
-The MC can have quite a lot of sex but be careful, being a dickhead can prevent you for getting the best ending.
-You have freedom while there are timed events and it has quite a few effects (Wars, the demon unification...)
2. Sengoku rance and big bang age: I put them in the same number because they are good games but what one of them has the other doesn't have it. Sengoku rance had a simple event system and easy to find the requirements to obtain the love from a character, in big bang age that part was hateful, another thing is that I hated the loyalty mechanic and too little turns for my liking.
On the other hand big bang age story and gameplay are better and more fun, even more the sex scenes with the heroines was a plus.
3. Kamidori alchemy meister: Best eushully game, it's quite long and with a new game plus, only problems that I find is that it was very vanilla in the sex scenes and that I always find it a bit of the bad side the ratio of sex scenes in the story, I always felt it needed more of them, especially with the heroines. Overall the gameplay and the story is totally okay, but not enough to get a better place.
4. Rance VI: I put it here mainly because of the big grind it requires especially related to orbs, it has the best storyline of all rance games and it's quite dark, which I totally like. The bad thing is that it becomes quite grindy after some point in the game and it has some unfair fights that when you get them at first... you will probably fail. One of the funniest characters for me in the game was Megadeath, I liked her quite a bit.
5. Artificial academy 2: Very interesting game with a lot of things to do. It has quite a variety of fetishes, characters with different personalities... but if you don't have a lot of experience you will feel lost, meh this is a hate-love relationship.
6. Bunny black series: How can I forget this one, interesting MC, good enough story, good sex scenes... even so it was a bit too much on the light side for my liking, I expected at first demons to be more chaotic you know?, liking to have more sex if you know what I mean.
7. Leane of legitimate crown: This game could have been in the top 3 if it wasn't for it's many limitations, for those that don't know it, it's a strategy game with NTR elements, basically you have female generals and if they get captured they get raped until they join the enemy and you have a bastard king that wants to have a lot of children so he wants to get the girls to service him. In paper feels interesting but:
-First of all the king is just annoying for me, it should have been kicked away of the game and expanded the scenes with the MC and the enemy.
-The game overall is very easy, even when I played in black difficulty I found it too easy to win, so you won't feel any situation in which you will have to lose a female general or even risk it.
-It lacks time based events or things that push the war a bit more. Remember what I said in kichikuou rance? welp this one lacks it.
8. Life is paradise: It's quite a light hearted game but it's interesting enough, you can marry and have a child, get materials to make houses and other buildings and things like that, and a bit hidden there is a storyline that divides the 3 acts of the game. Even more the sex scenes with other characters are interactive, which is good and bad at the same time. For me what it lacked was giving fetishes to the MC and characters of the game and relationships with each other with marriages and things like that. Basically giving more life to the village in that sense.
9. ROBF series: All of them are good battlefuck games, quite impressive btw. The bad things is that the creator was a hater of gaijins so he made japanese puzzles to stop them from playing his games and things like that. Even more while the battlefuck is great, the storyline or other elements aren't so good.
10. Monster girl series WITHOUT paradox: On the storyline part it was meh, the combat wasn't good but... it just worked quite well overall, many fetishes and situations, however the linear story without any options at all and without any effect that the player may have (except joke options that get a bad ending) makes it borderline 10 and almost an honorary mention.
Now let's give a few honorary mentions:
-Oyako rankan: It's a game with exactly what I love in a game, having the risk of losing and being able to get a harem if you do things well enough. Basically you get NTR, get a girl or get a harem depending on how well you play it.
-Sangoku hime and related games: Basically good strategy games, quite funny to play and with faction options.
-English hentai game mentions:
*XXXivilization: A game with... quite a bit of ambition, while at the moment it needs a lot of work it could become a great gem in the future
*Seeds of chaos: I would say that it is currently the english hentai game with the highest quality at the moment. Even more it has a dark storyline and feels good to play (only bad thing is that it doesn't take the dark side to the sex scenes, making most of them optional).
*The company: It's a very good game, the bad point for me is that the more I see how the serums work the less I like it, personally I think it should have been more related to characters traits and fetishes and less towards specific actions. For example let me say how I would have liked the serum system to work on Dakota (the sister) and just saying but it doesn't follow an order within:
1º Serum options:
-Incest awaikening: She will see her family as potential relationship partners and will be able to feel lust for them.
-Sexually extroverted: She won't shy away from sex talks or porn, in fact she may even invite you to see it together!
-Exhibitionist: She isn't shy and likes to show her body when she has a chance. However she will only do it if she has some level of trust with the person which she is showing her body.
2º Serum options:
-Lustful: She may want to have sex at different moments and places of the house. It will make her horny from time to time.
-Active rol (exclusive): She will prefer to be in control of interactive scenes or any other scene that she can.
-Passive rol (exclusive): She will let the MC to choose all actions in interactive sex scenes.
3º Serum options:
-Free spirit: She will have sex with any person that she likes, won't be limited to the person she likes the most.
-Dominant rol (exclusive): She will like to dominate her partner on bed.
-Submissive rol (exclusive): She will prefer to be dominated by her partner on bed.
This change the interesting part would be that it becomes traits, even more it opens the possibility of opening those traits without a serum.
*Adventure high: Interesting game with multiple paths, the combat isn't great but overall is more than good enough.
