I am also stuck on that mechanic part. hence I'm bouncing around on a platformer in godot or Game maker and a standard RPGmaker game without a combat mechanic. Combat mechanic is way overdone, fantasy, modern, sci-fi, it has all been done and done again. Rythim and that bullet hell stuff is also overdone.
Since I'm aiming on the lewd and the sort of dance/sing contest competition I am thinking of somhow using those mechanics but altering them to be something unique.
There's already game out there that simply conveert the damage varable with the pleasure variable or orgasm counters that depletes HP or intrease the plasure guage in a sort of turn based combat mechanic, I seen those that alters between traditional combat and pleasure based, I even seen 3d real time mechanics of both battle and quick time events for lewd events (the lewd events seem to take longer time than fighting directly and while in that state other enemies can walk up to the player next in line to either fight or screw).
Personally I think I have the feeling of having that laid back sort of turn based combat, can't really do my business when I have to pay attention to real time quick events, but maybe if it's just couple buttons you can do on one hand. but I would also like a stimulating button masher for alternative minigame that's also lewd.
Still thinking of the same old game mechanics, does it really matter if it's the same formula just rehashed a little differently? I could always demand the playerbase to correctly recite "the river flows into you 😂" in 144 bpm in midi keyboard but that would be stupid and I hate games like that.
Also, absolutely hate text based adventures. If a rpg has that I just skip the text and then keep checking the personal info mirror to see any effects the text progression has on the character, quickly ignoring all the other characters involved. If it doesn't even change the character sprites I quicky lose interest. a game needs a visual appeal. I probably want to tell a story through animations and less through words words words, while not being cryptic with it (still give clear objectives with it detailed in a quest log).
