Oh, I like RPGs and Adventures too. Well, as my avatar shows, I'm a fan of Zelda.
I don't like shooting games either.
Actualy, when a game begins to have lots of coding, I get lost and forget it. :-/
I'd like to make big games, but lots of them are still waiting for bugs resolve, time, and motivation. ;-D
But there are people who can program or modelise 3D things for hours, without getting lost, tired or bored. Maybe you're a person like that. Then, as my friend, you'll succeed in doing any kind of thing on a computer. Though if you're like me, you may need a certain amount of luck to be able to finish the making of med-size game without getting crazy!
