Best Rare/Underappreciated Game?

Now that the gamecube has finished its life as a box, i find myself looking for gcn games to play on the wii. no more games are being made and we can now look at the purple box as a whole. in your opinion, what was the best game that was just not appreciated, flew under the radar, is a rare game and should be played, or just a diamond in the rough?

for me, i am def. going to say killer7. it has so many levels, whether those are intended or due to its confusing, complex nature. either way, its a unique experience (a FUN, unique experience) that I havent played anywhere else

• Cel Damage - cart racing game that was overshadowed by Mario Kart - I thought this was much more fun and creative.

• ESPN International Winter Sports 2002 - not all the games are fun but the curling and bobsled events are fun.

• Grooverider Slot Car Racer - only slot car game on the Cube that I know of and it's quite fun.

• Monster Jam Maximum Destruction - Monster Truck game that has a great mini-game where you knock others out of the ring.

• Need for Speed Hot Pursuit 2 - racing game with cops that while not rare, I think is definately underappreciated.

• Pool Paradise - best (and only?) stand alone pool game for the Cube, the gameplay is great, the characters and setting are not.

• Roadkill - vehicle combat game that has story and very fun multiplayer.

• Speed Kings - motorcyle game, like Road Rash of old but better.

• Worms 3D - a departure from the 2D experience but very fun once you get the hang of it, but it could have used a bit more work.

Indeed! My other choice would be Beyond Good and Evil

Pikmin 1, it was the basis for a superb sequel and a lot of people say it is too hard, but I played it again a few weeks ago and I completed it.

Metal arms: A Glitch in the System

44 long levels

solid multiplayer

no ones heard of it

Alien Hominid. Its a great game but no one buys it because of the graphics. A lot of fn though.

Eternal Darkness. I don't know how popular it was or talked about it was, but that game was awesome.KatanaMaster_17

Yeah, I think it's better than Resident EVIL!

I'm sorry that nobody else seems to think Star Wars Jedi Knight II: Jedi Outcast is worth anything. Personally it's my favorite game, next to Smash Bros of course.

Great game, but the gamecube version was bad. After I played the pc version, I just wonder what went wrong. But that game was highly praised at the time.

Personally, I thought that Warioworld was very under-rated. Definitely one of the best platformers I've played on the Cube. Creativegameplay,fun bosses;It definitely deserved more than a freakin' 6 from GS.
