Building a world map alone is something that could takes up days, regardless of the inherent simplicity of such an act. Creating characters, items, monsters, special attacks, and cities is fun, but tying them all together, knowing when and how to introduce them into what will become the finished product, well … it's hard. Making a game is hard! It's work! If you have the drive to make a game using RPG Maker 3 as a base, congratulations, your organizational skills are somehow better than mine. The game is a powerful and easy-to-use tool, and you'll no doubt use it many more times in the future, although you may not be impressed by the mediocre graphics. As for me, I'll just stick to writing screenplays.
