Eventually I would like to make an rpg, but after trying i feel that i have gotten in over my head. I have coded tetris, breakout and so on, and I had no problem. They took me a few hours but what should I do now? I have been designing and coding a tile engine but it just seems so hard to approach. Is there a type of game I could make in a matter of weeks or maybe a few months rather than years which the rpg would take? I need something to help prepare me.

Try to make a side scroller like Raiden or one of the Marios. They are more complex than a single non-moving screen type game, but not as difficult as an RPG.
