Don't forget Resident Evil 4...

Anyway, it's the Nintendo first/second party titles that make the Gamecube a required purchase for me (along with steadster and asnozz, by the looks of things). Of course that isn't to say that other consoles aren''t worth owning, that'd be dumb.

 

Don't Forget (mostly non-exclusives but with good cube versions): (numbers in brackets indicates an equally good sequel)
Super Monkey Ball (2)
Viewtiful Joe (2)
Harvest Moon
Mario Golf
Soul Calibur 2
Donkey Konga
DK Jungle Beat

 

Actualy, I remembered all of those, but:

Resident Evil 4 - Comming out on PS2
Super Monkey Ball (2) - latest version on XBox and PS2, and combines the maps for the GCN originals
Viewtiful Joe (2) - Available on PS2
Harvest Moon - Somehow I didn't find it to be that fun.
Mario Golf - I havn't played it but i've heard its not very good from several people I know
Soul Calibur 2 - Available on PS2 and XBox
Donkey Konga - Yea, I probably should have included this one
DK Jungle Beat - Havn't played it, hear its very short though (six stages was it?)

 

Yep, but they're all still v good cube versions

Resident Evil 4 - Comming out on PS2
Yep, Cube version looks prettier and better though

Super Monkey Ball (2) - latest version on XBox and PS2, and combines the maps for the GCN originals
Yup, but cube versions are still worth it since they're pretty cheap nowadays

Viewtiful Joe (2) - Available on PS2
Just your personal opinion as to which to go for here

Harvest Moon - Somehow I didn't find it to be that fun.
I liked it, and it got pretty good reviews - i can see how people wouldn't like it though

Mario Golf - I havn't played it but i've heard its not very good from several people I know
Hmmm, I enjoyed it a fair bit, but again, your mileage may vary...

Soul Calibur 2 - Available on PS2 and XBox
But without link on them!

Donkey Konga - Yea, I probably should have included this one
Yup.

DK Jungle Beat - Havn't played it, hear its very short though (six stages was it?)
Quite short yup, But fun none-the-less, and I still play it despite having semi-completed it - until you get platinum on all levels, you haven't fully completed it in my eyes
