Would make a game like this myself, but my art skills are mid and making a game is pretty long and hard.
there are already similar games for each part that you want.
and i suspect you want it because you played and enjoyed them before.
TLDR,you want a mix of game into a coherent plot and all in a single game.and maybe make them animefy*?
and make it a mod for flexible switching?
Ps,you can pray or wait but I think the game you want will 99% NEVER come true,not until we have some popular skilled modders or $ backed modders and huge community contribution.
Here's the maths,
(for high quality mod,eg no weirdly forced reuse face or ear)
-for each race it would need minimum 2 spine art per race,=1 for adult,1 for child form
assume 1 for idle and xxx stuff. at least that's how MBM code design is.at each room they then has their own copy of parts or whatnot.
1 spine has many pictures/position*.
eg,milking,idle heal,sxx w golbin,sxx with orc,.......=at least 12 for base,13 with dlc tentacle,
ok so 1 new race=2*13 for base
ok lets say we add a new position(like kiss while hugging sxx in vip room)
now great for each race we already have in game they also need that i think our game has 8 race?(hu,dra,dwa,elf,hit,neko,dog,rab)
wo succubus
ok now great,good luck drawing 16 sxx position for them,is what I would like to say to make you give up.
BUT.its COULD be14.
human dont have tails or whatnot, you can think of it as base*body and cut cost reuse the stuff from dra*.so(dra,dwa,hit,neko,inu,elf,rab)
7 for each age state*.
14 for both,(can minus 1 well i dont think rabbit young or old change that much,but yeah)
so lets say at least for prototype you and x modder want to mod to prove its possible to add a brand new race and new xx position you need to draw.....
(2*14)new race,(age*actions possible)
+
(2*8)to make older* race also have that sxx position.
=44 anim sprite.(FOR mod MBM ONLY)
and assume you can do 1 per hour then yeahh i guess 1 week is gone by common work hour rule,
i mean some is not THAT hard like for example if you animated sxx with neko you can copy paste and edit from there or base of current existing sprite reposition or rescale...But still you need to DO IT once.
_________
say if you add the dungeon defense thing there is a possiblity for a brand new spine and sprites....(depends on what is the artstyle and method to play or whatever.)
-this...8 girl +5 monster,13 spine ...good luck and yeah please include attack animation,walking,idle,whatever.....)
=13*n animation,where n is how much state* you give.
The cost to mod assets will not change MUCH,UNLESS we have someone smart enough to do heavy modding to cut cost or whatnot.
However if you REALLY are going to do it,ping me with your email i can even give you some extracted stuff and let you quickly try edit.
and also try contact surgy or other modders.
