Reddit reviews Learning Cocos2d-x Game Development

Basically you want to become a game designer. There are a lot of people like you, just take a search on forums of gamedev about "I've an idea", "An idea for a marvelous JRPG" "I want to start a game of my own", etc. you'll find thousands of post everywhere online, and maybe, tens of games from these people? My point is, are you determined? Do you really want to do it? Are you willing to use the money you spare in a productive way? Study game design and programming, and don't start easy, start hard, choose a game framework or engine and buy a single book on how to create a game with it (just as an example if you choose Cocos2d-X you can start with Learning Cocos2d-x Game Development). Spend three months just learning and training your capabilities, recreate simple games like Tetris, Arkanoid, etc. then try to participate some game jam on itch.io or your favorite game jam site. Collaborate with others in teams on game jams to learn how to teamwork (that's a very hard side of creating a game). In the meantime continue to collect money and then, when you'll feel really ready, hire some graphic artist, a musician and start your big JRPG project.
