-Metroid Fusion. I got stuck on a boss and I haven't gone back to it.
-Metroid Prime Two, I got to the last boss, beat the First boss after about 10 tries, then got destroyed by Dark Samus.
-Metroid Prime Three, I got halfway through, then I bought the trilogy on Wii and started the whole series over. I'm halfway through two, hoping the new controls will make dark Samus easier.
-Majora's Mask, I really want the Fierce deity mask, but I can't manage to beat the Goron section. That and I moved for uni so I don't have an N64 at the moment.
-Final Fantasy VIII and XII, I got about 3/4 of the way through, and now I no longer have the memory cards they were on.
