IMNEWATTHIS'S PROFILE

Hello everyone, as my name implies, I am completely new at this and I have all the free time in the world, so I want to do something I've always dreamt of doing as a child: Making a video game. The problem is though: I have no experience in making, designing, coding, etc. As stated before, I have too much free time, and while I can understand that creating a game from scratch takes a while, especially by one person, I still want to try my hand at it. So, this leads me to my first question: What do I need? I understand that this is an RPG making site and I want to know what should I download, what does it do, and all that fun jazz. I understand different programs may be needed for different genres of games and RPG's, so the type of game I wish to make is similiar to that of the Mother series, namely Mother 2, or Earthbound for the SNES as it's called in the U.S. So, what do I need and what should I do? :) Thank you for all your help!
