Mad world is probably one of the best uses of motion controls in an adult game for the wii imo, you'll break a sweat too and get some good exercise as you repeatedly smash guys faces into "rosebushes" on the walls. Not sure about in Brazil but that game goes for about 3-5euros used here at retail in Ireland, should be a bargain price if you shop around.

If you can find it, Battalion Wars II

If you like exploration maybe look into Endless Ocean 1&2.

Also, maybe it's just my taste, but I am gonna have to downvote on MadWorld, definitely my least favourite Wii game I played... It looks great, and it was neat trying out the different styles of kills the first few times, but I thought it got boring about half-way through (which is about 2 hours in). I am not the biggest fan of beat-em-up or hack'n'slash type games though, so perhaps I am not the best judge. (No More Heroes I liked though, and thought it got better and better as the game went on)

You mean to import it!:P

I didn't see how to delete my duplicate post, so I replaced it with this text. Is there a way to delete?

Amen to this.  It was lauded for its mature style and visual aesthetic.  5 minutes into the game I knew I had the most linear bore-gore fest of the generation in my Wii.  Popped it out and never looked back.  Definite example of style vs substance.

BIT.TRIP Complete - On-disc collection of the 6 BIT.TRIP Wii Ware games (Beat, Core, Void, Runner, Fate, Flux). Each game is a modern music/rhythm take on an old classic. For example, Beat is a take on Pong, where you have "bits" coming at you in patterns, and on the left side of the screen, you have a Pong paddle that you have to use to hit them back. Each bit you hit adds a note to the music (and then another note when it leaves the screen). Nothing else like, them, really. The "Complete" version comes with a soundtrack CD and adds checkpoints and some other things (leaderboards, maybe?).

Zack & Wiki - Like old point + click adventure games, but instead of a large world that you're navigating through, it's broken up into self contained levels. It's VERY challenging and very Japanese in it's style. It's a single player game, but my wife and I like to play it together, brainstorming the solutions together and taking turns using the controller.

Geometry Wars: Galaxies - Twin stick shooter with awesome visuals and music. Only version of Geometry Wars to make it to a Nintendo home console. Comes with the original "Retro Evolved" game, but the main "Galaxies" campaign siwtches things up with upgrades, differently shaped maps, and objectives.

Little King's Story and Sin & Punishment - I own these but haven't actually played them yet. Little King's story is a RTS/Life sim/RPG that is unlike pretty much any other game on the Wii (or maybe any other platform). Sin & Punishment is the sequel to a Japanese-only N64 game that is sort of a cult classic. It's an on-rails shooter where there characters have jetpacks (that was enough to sell me on it).

Boom Blox - Really fun competitive party game. You use the motion controls to "throw" balls at Jenga-like towers to knock them down.

You can just buy physical Wii games too.

I think I would give that prize to The Godfather: Blackhand Edition.

Trauma Center Second Opinion and New Blood.
