Yes. ( not to dis RPGM it has many decent games & im quite sure i havent explored even 5% of the rpgm list ).
Im playing adult games for only like a year now, i preffer to play renpy games first. I bookmark decent looking rpgm for later.
Some of the main reasons im not doing rpgm first are.
1. Cant save whenever / wherever we want.
2. Many rpgm games doesnt implement roolback for dialogs.
3. Crash in the middle of game sometimes. ( if crash happen in renpy, there will be some auto save in save menu for it ).
4. Most does no have extended save slots. ( i save some lewd locations that occur during grind which will allow me to replay a specific character path again whenever i want without too much grind. ive like over 70pages saves in some renpy games like holiday island, milfy city, foot of the mountains, etc. i miss that in many rpgm games ).
I have played some recommended rpgm games like pesants quest, long live the princess, etc. still many good recommended rpgm games like lust epedemic, my new life, milf control & many more games are piling up in bookmarks while im checking out renpy games.
