I suggest: Mario Galaxy, Metroid Prime 3, Zelda: TP, SSBB, Mario Kart Wii, Zack and Wiki, VC ganesm Wii Warer games, and other good games I'm too lazy to list.

 As another Belgian, I'd have to say that I have absolutely NO trouble finding anything for the wii.  A friend of mine wanted a wii, and got one instantly (and that was during the past Christmas holiday).

What? No metroid prime 3 on that list? I recommend the game anyway. Really good story too. Get the previous ones if you don't want to feel left out on the story though. It may be too hard for you though, because alot of people think that metroid games are hard.

I've played all the games on your list, so I'll tell you what I think:

-Zelda: One of my favorite Zeldas, if not my most favorite. Think of it as a beefed up version of Ocarina of Time. If you liked that, you'll like this.

-SMG: One of my top favorite games of all time. The level of creativity is ridiculous. Definitely a must buy.

-UC: It's a nice recap of the RE series. If you enjoy rail shooters or even just RE in general you'll like this. It's not very deep besides upgrading guns and finding all the files, but it's good for some quick entertainment. It also has some decent co-op that's easy for anyone to pick up and play.

-NMH: It's a rather short game (you could probably beat it in 10 hours on your first play through if you really tried), but its cast/story are crazy and has great gameplay. I actually beat it way too fast because I'd hurry from one boss fight to the next just to see who it was. It's one of those games you won't mind replaying a few extra times. I'd say it's also a must buy.

The Legend of Zelda: Twilight Princess (A, great Zelda story)

Super Mario Galaxy (A++, no story but gameplay is phenomenal)

Resident Evil: The Umbrella Chronicles (~B-, great RE story)

No More Heroes (~C+, it's by Suda; it HAS to have an f-ed up story (and watching some YouTube vids... it does).)

Current RPGs:
- Fire Emblem: Radiant Dawn
- Dragon Quest Swords

Upcoming RPGs:
- Fragile
- Harvest Moon Frontier
- Final Fantasy Crystal Chronicles: The Crystal Bearers
- Final Fantasy Fables: Chocobo's Dungeon
- Oboro Muramasa Yōtōden
- Monster Hunter 3
- Tales of Symphonia: Dawn of the New World

Current Shooters:
- Medal of Honor: Heroes 2
- Metroid Prime 3: Corruption (No online, but you should get it anyways.)
- Boom Blox (:P You shoot things, buy it anyways!)

Upcoming Shooters:
- The Conduit
- Red Steel 2

- Call of Duty 5
- Disaster: Day of Crisis (3rd-person most likely offline shooter)

I also highly recommend Sonic and the Secret Rings (has a light RPG system which I really enjoyed), Guitar Hero 3, Super Smash Bros. Brawl (a little) and Mario Kart Wii.

buy no more heroes. everything else is secondary

If you're a PS3 fan I'd suggest Metroid Prime 3. It's an epic shooter/adventure with pretty darned good graphics.

^^'' I am surprised Zuhyc that you will buy one;..(Yeah it is me konnichiwa).

Maybe you should tell us what you like?

I know that you are a Metal Gear fan but are you also a JRPG fan?

Cuz you for sure need to check Tales of Symphonia and if you really are a fan of RPG's and games like Final Fantasy, Then bro get also a DS...

You liked Final Fantasy Tactics then you will be very happy to know the second one is on the DS and the remakes like FFIII are very good.

Well my favourite games on the Wii so far:

SMG
No More heroes
Metroid Prime 3
Legend of Zelda
Zack and Wiki
.....


And then their are a lot of games coming that you probably will enjoy like tales of Symphonia and Brawl....(hopefully more will be announced at E3)..

You will love Boom Blox, and your sister will too. This is a GREAT game that is amazing for gamers and non gamers alike. Everyone i know who has played this was completely suprised at how good it really is.

There's the winning post - i'd disregard the rest of the posts and concentrate on gettin those 5 games.
