Well, this project is quite far off, I still have to complete Glassix and Lust Complex so about 3 years at the current pace, there's still a lot for me to plan for it but if you want more details about it, here it comes.
But first, do you read manhua? I guess most people here should read these, H-games often go in pair with manhua
(For those who don't know what manhua is, it's simply eastern (chinese/japanese/korean) comic books).
There are lots of different kinds of manhua but a recent trend is about isekai stories (isekai meaning reincarnation in japanese). Those manhua often have really similar stories: a guy/girl from Earth dies and is reborn in a fantasy world with magic while still having his memory for his/her previous life plus having a cheat power like super strength or unlimited magic etc...
So my idea is to make a game about such a topic with a wide panel of possibilities:
- Become an adventurer and raise the ranks in the guild
- Become a noble and raise the ranks to become a king, manage your kingdom and handle diplomacy with neighboring countries
- Become a demon king and destroy everything (or make peace with humans)
- Become a merchant and create your tycoon business
- Become a pokem... monster tamer and catch them all
- and so on...
Unlike Glassix which is one long story, this game will be played in lots of different stories with different worlds and objectives to fulfill with the help of those cheat powers which you'll unlock by completing the objectives. Each time you start a new story, you'll be able to unlock a new cheat power so that the game is easier (if you want it so). Each world would have a dynamic demography and economy meaning kingdoms could raise and fall, the player could cause a genocide of monsters to free the world of them, prices of items will fluctuate depending on the players actions, etc...
I'll also focus this game on shared community content by creating interfaces to easily create characters, worlds, events and stories, big or small then share them with players and get a rating system up to find the most liked stories, characters or worlds. Some creators might just have inspiration for 1 character which could be added to any other world or they might have an idea for a complete world and plot with exclusive npcs.
Depending on the story and what the creator chose, the player will have access to different interfaces
A VN interface to advance the story
A rpg interface similar to rpg maker when exploring locations or dungeons
A strategic board when handling kingdom and cities management or invasions
and lots of other interfaces to handle each other aspect of the game (status, spells, bestiary, quest logs, etc...)
You were asking about mind control and it'll come in several forms in the game, could be a spell, a potion, a cheat or whatever the creator decided. In the end, you'll be able to have any npc submit to you depending on your mind control level and the target resistance. You could control a simple peasant girl for fun or order a lady warrior to protect you or manipulate the queen to climb the ranks in the country. There will be different ways to use them, not just sexual this time
This is a huge project, much bigger than Glassix and a lot of stuff here are still only some general ideas which I'll need to organize better in the coming years. But this should give you a rough idea
