Try to look at other aspects of game development and game design that may interest you - maybe level design, art or other aspects may be more to your liking. I agree with the checking out some engines that handle that for you such as RPG Maker - allowing you to focus more on the other aspects of developing a game.
Something else you could try is to make a play on the some assumed rules of certain genres. Or instead try to expand on those rules in your own way - for example an RPG where you can try to talk to goblins and the like instead of fighting them. I'd say take a look at some old rogue-likes that try to let you do as much as possible for some inspiration!
