If you put in the effort to polish the scenes, mechanics, and overall feel, then with a great idea and a few iterations, you could potentially build a sellable game. I honestly do not know what it takes to sell a game, but if you have a strong idea and want to put it online, a tool like this can take you surprisingly far and let you focus on the bigger-picture parts of the game.

I think it's quite impressive without even trying it. I think more and more tools like this will pop up soon.
