There is quite a few I haven't played, but I had played them briefly to claim that I have actually LOL OMG I PLAYED THIS, IT WAS SO AWESOME
Orcale of Seasons/Ages
The Wind Waker (I have played this only a few times, and I can say this is one game I really want to play)
Four Swords series.
I am thinking about actually trying to buy them soon, but I also don't want to waste it cause I know I probably won't be able to finish them once I get them due to the amounts of events I am in recently
