to just name two off the top of my head...

-Metroid other M. I didn't like it as well as the Prime games, but it was still great...despite Samus being depressing..

-Epic Mickey. Sure, once the game was over, it was over (sadly couldn't see the ending again unless you played through again), but I loved it.

Madworld was a great game, I once saw it in a store for 5 dollars

Here's a really underrated Wii game: Calling.

It received mostly terrible reviews and I picked up for a laugh for $7 this past summer along with some other cheesy-looking games. Calling really surprised me. For a budget game, the scope and quality was fairly impressive. On top of that, it stands as one of the few horror games this gen that is actually focused on horror. Its atmosphere is thick and moody, its controls are tight and it actually feels like a classic horror adventure.

I ended up beating the whole game (and now I have to do the NG+ which adds more chapters, etc). It really took me by surprise and is WORLDS better than the Ju-On Grudge game I rented...

If you want a good horror game, give Calling a try. It might surprise you. My only warning is that it is SLOW PACED- you need to sit down and set aside time to play and enjoy it.

Metroid Other M and Wario Land Shake it.

Zack and Wiki is definitely on this list. I agree Warioland: Shake It was good as well.

• Underrated:
  Anno: Create a New World (Dawn of Discoveries)
  Another Code R
  Disaster: Day of Crisis
  Eldar Saga (Valhalla Knights)
  Endless Ocean 2: Adventures of the Deep
  Fragile Dreams: Farewell Ruins of the Moon
  Opoona
• Won't ever understand the haters because these are all 10/10 in my book:
  Excite Truck
  Metroid: Other M
  Super Paper Mario
  The Last Story

I also forgot to say Super Paper Mario. That game was a masterpiece in my mind!

You're awesome.

• Won't ever understand the haters because these are all 10/10 in my book:

The Last Story

Get out.

Other M is super underrated, unless you ask pixelman.

I wonder why Metroid Other M would be underrated... Hm...

Why wouldn't it? That is the dumbest question you could ask. Didn't sell the greatest and people across the board didn't like it, mostly because of the dialogue.

What's sarcasm?

It's hard to tell sarcasm when it is being written, but know that you mention it makes sense.

Batman: The Brave and the Bold. This game was overshadowed by Arkham Asylum which came out a year before. That and the fact it was based off of a cartoon series and that it was for the Wii probably made some people pass this one up. But I found it rather enjoyable especially in co-op mode. The story was decent and the game play along with the graphics reminded me alot of why I liked The Adventures of Batman and Robin on SNES. One of these days I plan on getting this game for my Wii collection.

• Metroid Other M (sales and reception)
• Xenoblade Chronicles (sales)
• The Last Story (sales and maybe reception)
• Wii Fit (reception)
• Metroid Prime Trilogy (sales)

Super Paper Mario - I still believe that people were disappointed in this game solely because it carried the Paper Mario name. On it's own it was it fantastic game with some really unique gameplay, great music, and an interesting story.

Metroid Other M - While the story is pretty "meh" the gameplay really works and makes you feel like the epic bounty hunter you are. The music wasn't quite as good as previous games, but the action payed off.

Epic Mickey - The camera wasn't good, but certainly not as bad as people claimed. I had a good bit of fun with this game even if its not perfect.

Basing this off reception rather than sales.

Super Paper Mario- No need to go deep into this. I appreciated it for what it was, and in that sense it was good.

Metroid Other M- I loved the gameplay in this. Both the gameplay and the ambiance immersed me. The story wasn't that bad to me, but Samus' story role and voice actor could have been better.

Spectrobes: Origins- I don't know why I have this. I don't remember getting it. But it was a pretty good title, with a neat battle mechanic.

Still thought Other M was a bloody good game.

Yeah, remember, I won't ever understand you.
I love The Last Story. One of the few RPGs I really enjoyed to play through (twice!).

Did I mention Fire Emblem: Radiant Dawn? Path of Radiance was a great title, one of the few in the strategy-RPG genre that I loved to play. It introduced me to the genre. It was easy to understand. Of course Radiant Dawn as a direct sequel was awesome. I think that one's underrated as well, but it's hard to recommend because you need to play the Gamecube prequel first.

Other M was a dream come true. A direct sequel to Super Metroid. It seems like I'm the only one respecting the revelation of Samus' real character. In a sense it was another layer peeling off. Like the first Metroid game where you found out that there was a girl in that robotic suit and not a man! Many people were upset and surprised. In Other M another layer's coming off and we have a look inside Samus. Aside from that mindblowing connection I thought that the story was pretty exciting, with how Ridley came to birth, and playing a detective game as who's the traitor. And also having some of the best bosses like Nightmare, Phantom, Ridley and the Metroid Queen combined in one game. I guess most people never played Other M through to the end.
And finally, since Skyward Sword got a Save File Update Channel I always thought Other M deserves one too. I never encountered the glitch, but for those who needed it Nintendo should have supported one. That's all negative I have to say about it. If I'm picky I could have wanted more iconic tunes. But the more ambient sounds are fitting the atmosphere, the rearrangements were still great, and the orchestrated music in the cutscenes, especially the ending song are beautiful. And the graphics are easily among the best on Wii. I could go on and on about why I like this game so much, and let me just say beforehand that haters are stupid.
