Hello there I got bored so decided to develop my idea, particularily the gameplay.
1) Worlds
A pixel map divided into region / countries and tree possible settings :
Contemporary - an 21th century Earth based settings, with Humans and no futuristic tech.
Might have to put a beastiality tag on this one as your character evolve from acquired genes so only breeding Human will only get you humanoid.
Fantasy - the classic magic world, different species : elf, dwarf, beastfolk, dragon, etc... you name it and of course MAGIC !!!
Futur - alien / cyborg (android ?), good old? laser rifle, force field, etc... the FUTURE !!!
Like CIV your early map is clouded and as you explore / conquer the world you unlock / discover it.
2) Spawns
Three diffculties :
Cave / Village - remote place, NPC got low combat power and you got less chance of getting spotted early game,
Town / City - NPC got medium combat power (police / militia), you got some hiding places (sewer), but your action can get spotted (citizen who disappear),
Capital - NPC got high combat power (police / militia), you got some hiding places (sewer), but your action can get spotted (camera, reported disappearing citizen).
3) H-Scene
(2DCG) It's through these that you get your DNA points to unlock perks in the Evolution Tree. You get DNA points by pleasure / actions / fertilised eggs / etc...
To unlock a branch you still need to breed the correponding specie, like you won't get claws and fur by breeding Human, go for werewolf / kitsune, whatever you got your hand on and float your boat, idem for gils & fins go for merfolk / siren, want tentacles ? Go for octopus.
4) Gameplay
Your objective is to conquer the world, pretty simple but to do so you will need DNA points, perks and units.
Your DNA Points / Perks depend on H-Scene, your number of unit depend on the number of captives, if you got 1 captive don't expect an army of 1.000 maybe a dozen to completely seize a Village or Town.
So Early Game you must get a broodmother to : get DNA points, unlock perks and increase your number. I see a zoomed in Map, infiltration gameplay, kidnapping, etc...
Mid Game you will have secured / conquered 1/3 to 1/2 of the world, 30+ Villages and 10+ Cities under your control with 100.000+ captives
And End Game the world is your.
You have 4 type of units to attack / seize cities and captives and to defend your territory :
Parasite - for infiltration, reconnaissance / spying (like CIV allow to discover the Map),
Fighter - for CQC and with low to medium combat power, charged with capture,
Artillery - for medium to long range combat and with medium to high combat power,
Guard - no combat power but high defense to protect other Units.
For "Attack Scene" you got a Map of the Village/City with specific location such as school, hospital, station, shelter, military outpost and you must dispatch your Units consequently like :
- you get your Fighter to school, hospital, station or shelter to seize civilians,
- your Artillery on military outpost, etc...
Can also get special "Attack Event" where the ennemy general (a woman what a coincidence !) is captured after a great fight and she get you more DNA points and some insider information.
PS : If you get Artillery Units to seize a village don't hope to get much captives, like really ? a cannon ? against villagers ? yep you will get minced meat.
For the progression something I see something like : don't pass your time in H-Scene or the Countries will launch a joint offensive on you during your sweet time and Game Over for you.
Well here my idea after a bit of boredom.
