Another idea for my RPG game is Friendly relations with NPC that allows you to get bonuses or even hire them to work for you. Reaching max level will let you invite NPC to live with you in bought house. Made so it is not really boring inside empty houses and you get passive benefits depending on NPC’s profession. Like Cook may do food for you while you adventuring.
however the most edgy idea of all that is Rebirth ability that gets unlocked.
There literally no Romantical stuff or even worse, just a button that not even have to be pressed near your guest. But basically means you will be reborn as your own son \ daughter.
Roblox Terms of Use prohibite any Romantical++ stuff between players, and there is just a small mechanic that may be considered as violation. Tried asking support but they didnt gave me proper answer and according to Terms of Use i probably can do that, just should not add Romantical+ Scenes.
