サキュバス戦記 (Succubus Senki) is an excellent, and very lengthy, doujin hentai game by 色仕掛けまとめブログ (irojikake matome blog/seduction compilation blog), made with SRPG Maker.
It is their very first commercial game release, and they put a LOT into it.
Plus, it’s available in English. The Japanese and English versions are the same product/files, so you can get it at a discount, apply coupons, and get points/cashback by using the Japanese version of DLsite.
Update: 色仕掛けまとめブログ (irojikake matome) are currently working on another game, using the artwork from Succubus Senki, plus additional artwork. Like Succubus Senki, the game will also feature the system where enemies attempt to make one last attempt to seduce you to save themselves.

The game features many enemy characters, all of whom have some form of hentai scene, featuring a lot of dialogue. There are also plenty of hentai scenes outside of combat, which typically involve a succubus trying to seduce you out of money, or something else, in exchange for “attention.”
Among some of the scenes are hand-drawn animations, and some, though not all, of the characters, have voice acting.
The developers have partially translated the game to English, and they are frequently updating it, so even those who cannot read Japanese can still enjoy it.
Storyline
Honestly, I skipped most of it as I was far more interested in the main content.
However, the gist of the story is: the succubus army is attacking human lands, so a group of heroes have to go and defeat the succubus queen.

I don’t play hentai games to engross myself in a literary epic, so a simple story suits me just fine.
There are a few side quests, as well, which feature unique enemies.
Gameplay
The way サキュバス戦記 (Succubus Senki) plays would, had it been any other hentai game, have been a great let-down in an otherwise excellent game.
The game uses the SRPG Maker battle system, which will feel somewhat familiar if you’ve played almost any tactics-style game (FF Tactics, etc.).
I, personally, loathe this system in hentai games as it results in slow, drawn-out combat. Not only does it take longer to get to the main content of a hentai game, but it restricts the times when you can save your game.

Fortunately, サキュバス戦記 (Succubus Senki) handles combat very well using the system. Combat sequences can be rather long, but they are still very engaging as every enemy has the potential to provide some “special attention.”
Hentai scenes and CGs
Hentai scenes and CGs are primarily accessible via combat sequences.
Enemies can attack any of your characters using “personal” attacks, which sometimes have a hentai, or ecchi, CG associated with them.
You can also make your characters “attack” themselves in front of enemies, and self-destruct. You can also surrender and beg enemies to defeat you using certain skills.

Some maps also have traps that can also result in hentai scenes, such as; flipping a switch to open a door, only to have an enemy seduce you into closing it in exchange for some “attention.”
Enemies will also try to make a final attempt to seduce you, when they take a killing blow, so they can turn the tables.
Update 2: For people interested in games with seduction, etc. CircleTeckA (known for their battle-fuck games) has announced today that they would like to create one.
The enemy who defeats your last character will also have a full scene where she has her way with you, most of the time there is a hentai, or ecchi, CG.
There is a large number of scenes, outside of combat, too. They’re easy to identify, as they have a heart mark on them, and some even have follow-up scenes.

A good example is a villager who seduces you out of some money, in exchange for “attention,” which then unlocks another scene where she demands more money and, when you give it to her, starts teasing you about what you had to sell to get the money to pay her.
If you’re looking for a hentai game with a lot of content, サキュバス戦記 (Succubus Senki) is one you should consider getting.
Where to get サキュバス戦記 (Succubus Senki)
サキュバス戦記 (Succubus Senki) torrents and downloads are easy to come by. But, as with the majority of other doujin products, it’s highly advised that you don’t traverse the high seas.
サキュバス戦記 (Succubus Senki) has undergone too many updates to count. Many of those updates being additional English translation, and even the addition of Japanese voice acting.
The most notable addition, which you won’t have access to, is the hentai scene replay room. Viewing hentai scenes and CGs without the replay room is quite tedious.
Get your copy from DLsite, and enjoy one of the few games in English on there!
