Coin toss, but not for me. You get an MC who isn't allowed to do anything to them. You essentially play cuck corruption as everyone else gets to make out with the girls, but you. Artwork nice, gameplay descent enough considering the price. DLC fine. Using money to buy explosives and throw at the main girls to speed through okay... being stuck watching all of the girls make out with anyone else besides you? Nope. Which is a shame as I really liked the idea and the concept. Just hated how it ignored you.

[/quote] [h2]Summary[/h2] [quote][b]Patch is not required![/b][/quote] [b]Operation Darkside DX[/b] is an RPG eroge that focuses on capturing, re-educating, corrupting, and training heroines. The player will take the role of the chief scientist of the evil organization, the [b]Forren Foundation[/b], and capture the members of [b]Holy Core Battlemaidens[/b] one by one and turn them into combatants. The game is not very challenging. If the player cannot defeat an enemy, completing [b]Resource Gathering[/b] provides extra resources to strengthen the party. Besides the 3 default combatants, members of [b]Holy Core Battlemaidens[/b] will also become playable after successful training. Although every heroine has unique abilities, the character balance is kinda poor. Late game enemies have very high attack and defense, making [b]Yakumo Nayuta[/b] almost the only reliable damage dealer[spoiler] (especially during the DLC chapters, where the party is limited to only 2 members)[/spoiler]. The game ha…

this is a very grindy game. you are expected to farm resources in between each stages to level up your team as it's a game over if you lose a battle in the main story. food gathering gives you a healing item but barely any research points or money. robbing banks gives you lots of cash but barely any research points. battle research gives you lots of research points and roughly around half as much cash as robbing a bank. the game also make sure you can't farm the same resource back to back as every time you clear it, it gets harder. under each task, there is a star. each time you clear that task, it increase by another star. for example, at main story 1-1, if you choose to gather food, you will meet 1-2 lv 1-2 enemies. when you cleared it and choose to go in again, it will be a 2 star challenge and the enemies will be 1-2 lv 5-6. i've not tried 3 star yet as my level is not that high. advancing the main story will also increase the basic level of the enemies in resource gathering. money is required to buy equipment and consumables. it is also used to level up your team. research points are used to train and convert any battle maidens you capture. there are some inconsistencies in t…

I am not a fan of the artwork and the cutscenes are a chore to watch. I am not a fan of ridiculously large breasts or milking. This game is very grindey. You spend a large amount of time leveling up. There isn't a whole lot of strategy aside from levelling up. All of the characters look the same, and the art is lazy. If you want a Hentai JRPG, I recommend tunnel escape.

So far you just play as a random scientist and do no actual corrupting. What the point in having a main character that does nothing.

For short, this game is definitely GOTY (Goon Of The Year) for me! I mean for H-Game with this cheap price, what more can you expect? This game has full Voice, plenty of scenes, uncensored, no patch required, and most important, this game completely fulfils its genre fetish. In term of story, it was quite short for non-segs scenes but this is good for me, because I want my ♥♥♥♥ rock hard from goon scenes not from frustrating boring long storyline. And for segs scene, it done quite well, even they reused scene but I think it quite acceptable. Since it was a chain scene and they changed image in details. For gameplay experience, I think it was a huge downside of this game. It has plain UI, some button that do action but no response in UI, required some grinding, lack of animations, and monotonous turn base gameplay. By the way, I think it's still acceptable for this game's price. Since it has auto system plus short non-segs scene as I mentioned above and simple straight line gameplay, it makes this game not frustrating to play. Finally, I think this game perfectly utilize its limited resource for indie game. It's not a good as normal game, but it ideal game for H-game.
