RPG Maker is a popular and fairly accessible piece of software for making RPGs (like the original Pokémon of Final Fantasy games), though it might be a bit expensive for beginners. You can create maps, characters, battles, dialogue, and inventories without code to build an RPG world and game for Windows, Mac, mobile, or web with HTML5. There are good tutorials on YouTube but the program is quite easy to start using.

RPG Maker includes a selection of maps and assets to get you started, but there are also a variety of free and paid DLC packages available for RPG Maker which include soundtracks, recordings for character voices, and art assets.
