Game Engine <> Success

Okay, I've been following several game engine forums (Unity, Cocos2D and SIO) and what I have learned is:

"Just because you use a game engine does not mean your game won't suck"

Sorry but from the oh 100+ games I've looked at, many of which I even snagged a free copy, frankly a lot of them are really bad. A few are playable and very few are what I would call good.

This isn't ALL bad because I'm taking it all in so when I finally release something; I hope it will be high quality and fun to play.
