Those things don't make a game "good" but I'd argue that 60 FPS is definitely better than 30 FPS. 60 FPS basically means better gameplay, which in my mind is paramount over better visuals. Hell, there are NES games that ran at 60 FPS.
The funny thing is that as far as publishers are concerned, the FPS thing goes both ways. If they can pull it off, like in the Master Chief Collection, the publisher is like, "Look! 60 FPS! This game is so much better now!" If they CAN'T pull it off, then they'll either say, "Well, we want to game to look the best that it possibly can!" (Naughty Dog) or "30 FPS is just more 'cinematic' (Ubisoft). Personally I'd prefer Uncharted 4 sacrifice some visual fidelity in order to get a 60 FPS experience, but that's just me. And Naughty Dog can't act like 60 FPS isn't a selling point. It was a predominant selling point of The Last of Us Remastered and basically every reviewer said the game was more fun at 60 as opposed to 30 FPS.
