Depend if the main gameplay is serviceable.Wind Waker is one of those Nintendo games that touches on a point I raised when critiquing Earthbound on here.
How do you deal with a situation where you can see tons of flaws in a game's mechanics and design, but the game is so charming that you enjoy it better than you would a similar game with better mechanics but less charm? How do you explain / justify that? Doesn't it lead to the conclusion that gameplay isn't the most important thing? That's something I find hard to accept - I almost always argue that gameplay is the most essential part of a video game.
I don't mind the DraQue-esque nature of Earthbound, I find it charming.
The truth is that gameplay isn't the most important thing because the resulting experience is a mix of more elements which can have different doses depending on the game but need to mix well together.
There are games that rely heavily on single aspect but those would never qualify to be a masterpiece, just cult classic at best (example: Killer7).
