Metroid Prime 3. Plus, you could tell us what other games you had. For example, I highly recommend downloading "Super Metroid," or buying the Megaman Anniversary Collection (it was for the Gamecube), but I do not know if you bought them or owned them for the original systems.
Ahhh. Well I have tons of PS2 games so I'll say that I have both the Megaman Anniversary Collection and the Megaman X Collection too. Anyways, I also have Okami for ps2, but I still want to get it for the Wii. I've got Resident Evil 4 for the cube, but also want that for the Wii. The games I currently own for the Wii are on the front page. But I know I should get Zelda, Brawl, Paper Mario, Trauma Center 1 and 2 (they are very good), I personally don't like Mario Kart so I'll skip that. I like Fire Emblem, but my friend owns that so I'll just borrow it. I'm going to also get Resident Evil: Chronicles because that game is badass and plays better than any house of the dead type shooter I've ever played. Whew. If anyone has anymore recommendations, just post it.
