@ Ash. Why the double post? XD
OP: So far you've gotten some solid retail purchases. But you may want to take a look into the Wii Shop Channel for some Wiiware titles you may find interesting. World of Goo is an amazing title that should be given a chance, you may also like Lostwinds, Bit. Trip. Beat, Bomberman Blast, the Art Style games, Tetris Party and many others.
If you never owned a Gamecube then it may be worth picking up a cheap GC controller and finding some great games on EBAY, or better yet go for some of the cool new play control titles like Pikmin and Donkey Kong jungle beat.
You might also want to check out some cool retro titles on Virtual Console, i recommend Zelda: Majora's Mask and Ocarina of Time as well as Super Mario RPG: Legend of the Seven Stars and the original Paper Mario, but there are loads of others out there if you're not quite into Mario or Zelda
How technical is your game?
