Do you mean Metal Gear Anthology or Metal Slug Anthology? I can't find any references to Metal Gear. There was a Metal Gear Solid Legacy Collection for PS3.
Whoops my bad, it is Metal Slug. lol
I fixed it.
I'd imagine the Wii version of Rodea the Sky Soldier would be difficult to find since it was only included with the first run of the Wii U version. Other than that, I can't think of any potentially rare or rare Wii games that haven't already been mentioned.
While I did get a second copy just to make a Wii version. While the collector's edition is rare the regular copy is petty common and as far as I know off all copies came with the Wii disc.
Damm do I see some awesome wii USA exclusives in there wich I haven't heard about, it can really suck to be a european collector at times 
You guys get a few exclusives I wish came out here too, Project Zero / Fatal Frame 5 for Wii U is one.
Coraline for the Wii
I have a copy, I've seen it quite often so I never thought of it as "rare" but some on the list are like that too. lol
now the PS2 version is hard to find, I haven't seen one in years.
Here are 2 games sniper elite and walk it out these were pretty hard for me to find and only seen them once. Also not really pricey but only seen once was aliens in the attic and yogi bear might as well add back to the future to the list also.hope this helps.
Walk it out I see on so many lists as a rare game, my local used game store has a couple copies. I see this game ALL the TIME. I have no idea why its on so many lists. Maybe my area just got a huge supply of it. lol I have a copy of it. I added it to the list just because I see it a lot others might not. But I'll keep an eye out for the others. Especially Back to the Future because it has held on to it's value.
Fatal Frame: Maiden of Black Water
If it was released in psychical form in the USA I would have bought it day one. Best I can do is get a European copy and mod or get a PAL Wii U.
Metal Slug Anthology may be rare, but in this case, I seriously doubt it's the more sought-after version. I mean, would you rather play that with the stupid WiiMote or a PS2 controller? And yeah, there's the Wii Pro Pad, but even that is stupid since you have to have it chained to your stupid WiiMote, and I'm not entirely sure if it's compatible with MSA or not, anyways.
It's not. Wiimote and nunchuk only I'm afraid. Though the japanese release supports the Pro Pad and the GameCube controller for some reason
I 100% agree with you, but this list is just about "rare" games not which is better.
im not sure if its rare but i have never seen any of the Kidz Sports wii games until this weekend when i saw my first one.
I think my local used game store has some of these games, not sure if they are "rare" but they are cheap. lol
