Links Awakening is the best.
There is a massive lack of Metal Gear Solid, seems like not enough of you played it. It takes MGS1 and makes it work with sprites, totally new giant campaign, incredible bosses, fun story, takes the best from the old metal gear games as well. Has I think like a hundred bonus missions. It's a classic.
Metal Gear Solid is a GameBoy Color game or it would have been my answer.
