Actually, I don't know if I'd suggest that. My favorite games are MMORPG
If you have some experience in coding, you might want to try an fps. They're not hard to code, only the bullets can be confusing in the beginning.
If you are still not in a state of programming a FPS-game, you can try a 2D-shooter, Memory game, A small rpg-engine(keep very basic) or maybe you can even try to design a small puzzle game.
