If you're going to buy Prime and Prime 2, you might as well go for the Wii Trilogy. Especially in Prime 2's case it fixes a lot of the originals' more frustrating flaws

Edit: unaware it was a necro, but my advice still stands

Metal Gear Twin Snakes, Jedi Outcast Sonic Gems Collection, Mario Power tennis, Kart Double Dash (dont let anyone tell you it sucks)

back in 2009 I discovered Tales of Symphonia and last year I played both Skies of Arcadia Legends and Paper Mario TTYD, both which I missed first time around

All the games I have in my GC wishlist. And I also still need to properly play many of the ones I already own, except for those which I only bought because they were in a bundle with the better games on eBay.

I bought Rogue Leader off Ebay last week. Love that game.

Viewtiful Joe 1&2 - tough as nails but fun and unique!

Luigi's Mansion - a mind blowing, masterful experience considering it's ten years old and going for $10 nowadays..

Twin Snakes - Snaaake?! Snaa-aaaake!!

Soul Calibur 2 (featuring Link!!)

F-Zero GX - simply a classic! (pro tip - do not attempt story mode until you've earned a couple of medals... learned that one the hard way...)

Wave Race - splendid water physics!

Billy Hatcher - liked it quite a bit, under appreciated IMO - it's a Yuji Naka game after all

DK Jungle Beat  - or check out the new play control version, made by the same team that brought you Galaxy! also an under appreciated game

IKARUGA - treasure's dualistic shooter of renowned legendary difficulty (and awesomeness!!)

last, but not least - the unfathomable bizarre-ness that is Yoot Saito's Odama! (of Seaman fame! )

If you're gonna do that then get Prime Trilogy for the Wii. It's better value, and better controls...

Also, don't forget Chibi Robo, Double Dash!!, Sunshine, Pikmin and Pokemon Collaseum. And Eternal Darkness. Those are my personal favourites

At no point playing this game did i wave my arms

Phantasy Star Online episode 1 and 2 are great. episode 3 is very unique. Pac Man vs is suposed to be a good multiplayer game. 

Really... what about the QTEs, like early in the game when Leon is running away from that rolling boulder. I know I was waving my arms pretty wildly. On Gamecube, you are mashing "A" button if I remember correctly.
