Choosing between a few ideas, Which to do?

I have been wanting to make a good game, with actual effort, but now I have three conflicting ideas.

Mushroom Kingdom Adventure: Heavily inspired by other games, an open-ended adventure in th Mushroom Kingdom, with a somewhat small environment but heavy interactivity. The game would be based on going around and gaining Mission Points to get to special places.
Super Mario World- Unofficial Sequel: Inspired by various fangames, a "sequel" type game (obviously) which introduces new elements and monsters. The game would be SMW graphics, with some customs and edits (Especially for the plethora of original elements)

And I haven't thought much of this other idea, but here goes:

Mario's Great Journey: A storyline based game, less open-ended than Mushroom Kingdom Adventure, but moreso than SMW: US. It would be sort of a linear but RPG-type game with a developed storyline.

All names are WIP, by the way.

Mushroom Kingdom Adventure

Mushroom Kingdom Adventure because it just seems so much more original than the other 2.

Well, the SMW: US, would introduce new elements not originally in Mario. (If I can think of any)

MKA is my least favorite choice, because most basic games are more fun.

Please excuse double post, but I reexplained some games.

SMW: US mainly because what I look for most in fangames is being a new game instead of a trimmed down clone, but still stays close to the originals.

Why not combine elements of all three?

That could just be done. New elements not in Mario, RPG elements, and a classic bent. Sounds nice.

I like love your idea.

SMW:US for new enemies.
