A game requires a lot of work, maybe you should try to learn how to make events properly by looking at tutorials and asking for help. You want to make the maps and the story which is practically creating the game and taking credit for it when the person who helped with the coding is just a helper. Imagine you creating the base of the game and someone helping you to spice it up with the events and such.
Making horror games is probably less difficult than making RPG games I think. You have a lot less work to put in such as less Items, less features, less enemies, less maps, less characters, less of even a story, less of practically everything and rpg games are generally a lot longer than horrors. You'll never be able to ever finish a game like that unless you get involved in a team. And in a team, everyone plays their part and knows where they are heading...
