No such thing except in your mind, which I suppose is all that matters. Since this is 100% opinion based, I'd say the game I found that I enjoyed the most, and was so good that any flaws were not even noticed, would be Super Mario World. But this was largely due to when I played it- I was a teenager seeing one of my favorite game characters reborn in 16 bit heaven. And it had YOSHI!!!
I'd never find a perfect game now. I'm just too old and cynical, and do not appreciate games like I used to. But some recent great games have been The Last of Us and (don't hate me) Dragon Age: Inquisition.
