1. Eternal darkness
2. Super smash bros. Melee
3. Pikmin
4. Mario Kart Double Dash
5. Luigi's mansion

1. Metroid Prime
2. Paper Mario TTYD
3. REMake
4................

That's my list. I really want to add Twilight Princess and RE4 but I guess they don't make the cut. Didn't like Wind Waker until the latest version (vastly improved IMO), was never into Smash, Eternal Darkness or Double Dash. So that leaves me with 3 games on the list. Everything else I played was ported to other consoles.

Writing this list is actually opening my eyes as to why the Cube didn't sell very well.....
