Create a plan! First of all if it is an RPG I would start with how the game will be setup. If it is an RPG the two main parts of the game should be storyline and character building. I would start by writing a general storyline and include character traits to all the characters you want, maybe along with abilities and powers. Next I would work on the engine. Now this doesnt have to look good at all during this point of development. You may want to scribble down on a sheet of paper where you want things like text boxes and health bars to be displayed.
The engine is practicly the main part of the game so I'm not even gooing to try and tell you how to code it. So pretty much the engine will include movement(with camera work), interaction with other characters(which should develop storyline),battle system(this can be turn based or real time), and last of all stats(which will need a LOT of variable work). If you get past this point you can try to get collision working in your game or I would recommend Nuclear Glory collision DLL, if you have enhanced or Pro.
Although this may sound pretty easy it is not. If you skip the planning process you will find yourself sitting at the computer staring and waiting for ideas to come up which will take longer then if you have already decided something and are coding towards a goal.
I am not going to discourage you from this because after you make or fail with an rpg you will have learned 1 or 2 things.
1.It takes time and devotion to make an RPG and not all progammers can do it, especially alone.
2.Bunches of programming
So go ahead and try and if you have any specific questions the forums will be happy to flame you and maybe even answer them
