Links/sites to find help specific for rpg maker fetish games ?

Looking to get into making a vore weight gain game but have want to get an idea of how complicated my ideas may be for a novice to code ie slime wife is eaten by monster but after 5 turns pass shes able to kill monster no matter health because she is able to devour it from the inside,ideas like that i just want to find a place or someone to talk to to get an idea of how far I can realistically take my game and yes I know i should learn more code before attempting, but this is more a passion project so it’ll be easier for me to work on gradually chipping away at it as I learn as I cant really do basic study as i always goof off or walk around lol

That sounds like a Doom effect from the Final Fantasy series, more or less. I think that’s replicable with certain plugins and states. I know there’s at least one discord with folks that could help - I just don’t remember if I’m still in it or not, haha…

Is there like one specific site for plug-ins? Heard about a lot of good ones

It depends on which version of RPG Maker you have. IF you have MV, I’d suggest the Yanfly Engine plugins set. Though there’s also a bunch of other options, like Himeworks.

Is the yanfly set ideal for a vore and weight gain system game?

I wouldn’t say it’s ideal, you can probably manage without it, but if you’re planning on doing other games besides the vore idea, it couldn’t hurt.
